Abstract
Reliable in-vitro digestion models that are able to successfully replicate the conditions found in the human gastrointestinal tract are key to assess the fate and efficiency of new formulations aimed for oral consumption. However, current in-vitro models either lack the capability to replicate crucial dynamics of digestion or require large volumes of sample/reagents, which can be scarce when working with nanomaterials under development. Here, we propose a miniaturised digestion system, a digestion-chip, based on incubation chambers integrated on a polymethylmethacrylate device. The digestion-chip incorporates key dynamic features of human digestion, such as gradual acidification and gradual addition of enzymes and simulated fluids in the gastric phase, and controlled gastric emptying, while maintaining low complexity and using small volumes of sample and reagents. In addition, the new approach integrates real-time automated closed-loop control of two key parameters, pH and temperature, during the two main phases of digestion (gastric and intestinal) with an accuracy down to ± 0.1 °C and ± 0.2 pH points. The experimental results demonstrate that the digestion-chip successfully replicates the gold standard static digestion INFOGEST protocol and that the semi-dynamic digestion kinetics can be reliably fitted to a first kinetic order model. These devices can be easily adapted to dynamic features in an automated, sensorised, and inexpensive platform and will enable reliable, low-cost and efficient assessment of the bioaccessibility of new and expensive drugs, bioactive ingredients or nanoengineered materials aimed for oral consumption, thereby avoiding unnecessary animal testing.

Abstract
Sample preparation involving the cleavage of proteins into peptides is the first critical step for successful bottom-up proteomics and protein analyses. Time- and labor-intensiveness are among the bottlenecks of the commonly used methods for protein sample preparation. Here, we report a fast online method for postinjection acid cleavage of proteins directly in the mobile phase typically used for LC-MS analyses in proteomics. The chemical cleavage is achieved in 0.1% formic acid within 35 s in a capillary heated to 195 °C installed upstream of the analytical column, enabling the generated peptides to be separated. The peptides generated by the optimized method covered the entire sequence except for one amino acid of trastuzumab used for the method development. The qualitative results are extraordinarily stable, even over a long period of time. Moreover, the method is also suitable for accurate and repeatable quantification. The procedure requires only one manual step, significantly decreasing sample transfer losses. To demonstrate its practical utility, we tested the method for the fast detection of ricin. Ricin can be unambiguously identified from an injection of 10 ng, and the results can be obtained within 7-8 min after receiving a suspicious sample. Because no sophisticated accessories and no additional reagents are needed, the method can be seamlessly transferred to any laboratory for high-throughput proteomic workflows.

Development of an immobilized-trypsin reactor coupled to liquid chromatography and tandem mass spectrometry for the analysis of human hemoglobin adducts with sulfur mustard. J Chromatogr B Analyt Technol Biomed Life Sci 2021; 1186:123031.

Abstract
Sulfur mustard reacts with blood proteins, such as hemoglobin, to form stable adducts that can be used as long-lived biomarkers of exposure. These adducts can be analyzed by liquid chromatography coupled to tandem mass-spectrometry (LC-MS/MS) after an enzymatic digestion step. The objective of this study was to develop trypsin-based immobilized enzyme reactors (IMERs) in order to obtain a faster digestion of hemoglobin than the conventional in-solution digestion. Trypsin IMERs were synthetized by grafting the enzyme on a CNBr-Sepharose gel and the influence of several parameters on the digestion yields, such as the transfer volume between the injection loop and the IMER, the temperature and the digestion time was studied. The repeatability of the digestion on three laboratory-made IMERs was demonstrated for pure hemoglobin and hemoglobin previously exposed to different concentrations of sulfur mustard (RSD inferior to 13% and 21% respectively) and was better than that obtained for in-solution digestions (RSD inferior to 28% and up to 53% respectively). A preferential adduction of sulfur mustard on the histidine residues of hemoglobin was confirmed, for both in-solution and IMER digestion results. On a quantitative point of view, the performances of in-solution and IMER digestions were similar, with the theoretical possibility to detect peptides resulting from the in vitro incubation of hemoglobin in pure water with sulfur mustard at 7.5 ng⋅mL-1. However, digestion on IMER proved to be more repeatable and 32 times faster than in-solution digestion, and a given IMER could be reused at least 60 times.

Abstract
Therapeutic monoclonal antibodies (mAbs) are dominating the biopharmaceutical field due to the fact of their high specificity in the treatment of diverse diseases. Nevertheless, mAbs are very complex glycoproteins exhibiting several macro- and microheterogeneities that may affect their safety, quality, and efficacy. This complexity is very challenging for mAbs development, formulation, and quality control. To tackle the quality issue, a combination of multiple analytical approaches is necessary. In this perspective, capillary electrophoresis has gained considerable interest over the last decade due to the fact of its complementary features to chromatographic approaches. This review provides an overview of the strategies of mAbs and derivatives analysis by capillary electrophoresis hyphenated to ultraviolet, fluorescence, and mass spectrometry detection. The main sample preparation approaches used for mAb analytical characterization (i.e., intact, middle-up/down, and bottom-up) are detailed. The different electrophoretic modes used as well as integrated analysis approaches (sample preparation and separation) are critically discussed.

Abstract
Trypsin is the most widely used enzyme in proteomic research due to its high specificity. Although the in-solution digestion is predominantly used, it has several drawbacks, such as long digestion times, autolysis, and intolerance to high temperatures or organic solvents. To overcome these shortcomings trypsin was covalently immobilized on solid support and tested for its proteolytic activity. Trypsin was immobilized on bridge-ethyl hybrid silica sorbent with 300Å pores, packed in 2.1×30mm column and compared with Perfinity and Poroszyme trypsin columns. Catalytic efficiency of enzymatic reactors was tested using Nα-Benzoyl-l-arginine 4-nitroanilide hydrochloride as a substrate. The impact of buffer pH, mobile phase flow rate, and temperature on enzymatic activity was investigated. Digestion speed generally increased with the temperature from 20 to 37°C. Digestion speed also increased with pH from 7.0 to 9.0; the activity of prototype enzyme reactor was highest at pH 9.0, when it activity exceeded both commercial reactors. Preliminary data for fast protein digestion are presented.

Abstract
Immobilized proteolytic enzymes present several advantages over their soluble form, not the least of which is suppression of autoproteolysis peaks even at high enzyme-to-substrate ratios. We have made immobilized chymotrypsin by directly crosslinking it with glutaraldehyde to produce polymeric particles. Digestion of two model substrates using the particles was followed by CE peptide mapping with detection by UV absorbance or LIF. Results showed that autoproteolysis was highly suppressed and that different storage conditions of the particles in the short term (24 h) did not affect digestion of denatured BSA. As well, the chymotrypsin particles were indifferent to the presence of fluorescein groups on a casein substrate. Glutaraldehyde crosslinking of chymotrypsin inside a fused silica capillary column to make an immobilized enzyme reactor (IMER) was achieved in a series of reagent addition and washing steps, entirely automated using a commercial CE instrument. Digestion of myoglobin in the IMER for 30 min at 37°C followed by peptide mapping by CE-MS of the collected digest allowed identification of 17 chymotryptic peptides of myoglobin, or 83% primary sequence coverage.

Abstract
Pepsin was immobilized on ethyl-bridged hybrid (BEH) particles, and digestion performance was evaluated in a completely online format, with the specific intent of using the particles for hydrogen-deuterium exchange mass spectrometry (HDX MS) experiments. Because the BEH particles are mechanically strong, they could withstand prolonged, continuous high-pressure at 10,000 psi. Online digestion was performed under isobaric conditions with continuous solvent flow, in contrast to other approaches where the pressure or flow is cycled. As expected, digestion efficiency at 10,000 psi was increased and reproducibly produced more peptic peptides versus digestion at 1000 psi. Prototype columns made with the BEH pepsin particles exhibited robust performance, and deuterium back-exchange was similar to that of other immobilized pepsin particles. These particles can be easily incorporated in existing HDX MS workflows to provide more peptide coverage in experiments where fast, efficient, and reproducible online pepsin digestion is desired.

Abstract
Aldehyde- and NHS-activated magnetic microspheres were used to immobilize trypsin (CHO-trypsin and NHS-trypsin), and their performance for protein digestion was evaluated by reversed phase liquid chromatography-electrospray ionization-tandem mass spectrometry using an LTQ Orbitrap Velos instrument. NHS-trypsin provided greater sequence coverage and identified more peptides for the digestion of bovine serum albumin. A 1-min digestion at room temperature using the immobilized trypsin also identified more peptides (96±6 vs. 48±1) and produced higher sequence coverage (90±2% vs. 75±2%) than traditional free trypsin digestion for 12h at 37 °C. Analysis of 15 nM (0.001 mg/mL) BSA digested by NHS-trypsin in 1 min at room temperature consistently yielded one detected peptide; 150 nM BSA generated 22 peptides. Peptide intensity and protein spectral count were used to evaluate the run-to-run digestion reproducibility of NHS-trypsin with a three-protein-mixture. Three high intensity peptides for each protein generated intensity ratios from 0.70 to 1.09 and spectral count ratios from 0.78 to 1.18. Finally, RAW 264.7 cell lysates were digested by NHS-trypsin for 10 min and 30 min at room temperature, 604 and 697 protein groups, respectively, were identified by RPLC-ESI-MS/MS, with a peptide false discovery rate of less than 1%. Digestion by solution phase trypsin for 12h at 37 °C resulted in identification of 878 protein groups.

Abstract
Aptamers are a new class of single-stranded DNA/RNA molecules selected from synthetic nucleic acid libraries for molecular recognition. Our group reports a novel aptamer column for the removal of trace (ng/L) pharmaceuticals in drinking water. In this study, cocaine and diclofenac were chosen as model molecules to test the aptamer column which presented high removal capacity, selectivity, and stability. The removal of pharmaceuticals was as high as 88-95%. The data of adsorption were fitted with Langmuir isotherm and a pseudo-second-order kinetic model. A thermodynamic experiment proved the adsorption processes were exothermic in spontaneity. The kinetics of aptamer was composed of three steps: activation, binding, and hybridization. The first step was the rate-controlling step. The adsorption system was divided into three parts: kinetic, mixed, and thermodynamic zones from 0% to 100% binding fraction of aptamer. Furthermore, the aptamer column was reusable and achieved strong removal efficiency from 4 to 30 °C at normal cation ion concentration (5-100 mg/L) for multipollutants without cross effects and secondary pollution. This work indicates that aptamer, as a new sorbent, can be used in the removal of persistent organic pollutants, biological toxins, and pathogenic bacteria from surface, drinking, and ground water.

Madru B, Chapuis-Hugon F, Pichon V. Novel extraction supports based on immobilised aptamers: evaluation for the selective extraction of cocaine. Talanta 2011; 85:616-24. [PMID: 21645749 DOI: 10.1016/j.talanta.2011.04.016] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2010] [Revised: 04/05/2011] [Accepted: 04/11/2011] [Indexed: 11/16/2022]
Abstract
A new kind of selective sorbent based on the use of aptamers and dedicated to the selective solid phase extraction was developed. Cocaine aptamer was chosen as model aptamer to demonstrate the feasibility of this material and to provide a complete evaluation of the synthesized sorbent. The effect of different parameters such as the nature of the immobilisation support (silica, agarose), the type of immobilisation (covalent or non-covalent) and the length of the spacer arm (C(6) or C(12)) were studied. Therefore, various oligosorbents based on different immobilisation strategies were synthesized and characterised by estimating the extraction recovery and the capacity of cocaine and the binding efficiency of aptamers. Control supports without immobilised aptamers were simultaneously studied in parallel to assess the selectivity brought by the oligosorbents. The oligosorbent based on CNBr-activated sepharose showed the best performances with an extraction recovery for cocaine of 90% while 6% was obtained on the control sorbent. The high selectivity brought by the oligosorbent was then illustrated by applying the oligoextraction followed by LC/MS analysis to a post-mortem blood (cocaine overdose). Results were compared to those resulting from a conventional protein precipitation procedure. The presence of co-extracted interfering compounds was strongly reduced with the treatment by oligoextraction. A limit of quantification of 0.5 ng/mL was obtained that is largely lower than the concentration found after a single intake of cocaine.

New extraction sorbent based on aptamers for the determination of ochratoxin A in red wine. Anal Bioanal Chem 2011; 400:1199-207.

Abstract
A new solid phase extraction method based on aptamers, an oligosorbent, was developed and applied to the determination of ochratoxin A (OTA) from red wine. Two solid supports were chosen to immobilize OTA aptamer by covalent binding (cyanogen bromide-activated sepharose) or noncovalent binding (streptavidin-activated agarose). The resulting oligosorbents were evaluated in terms of retention, selectivity, and capacity. To assess the selectivity of the resulting oligosorbents, control supports made only of a solid support without immobilized aptamers were simultaneously studied. After optimization of the selective extraction procedure, extraction recoveries close to 100% were obtained on both materials. No retention was observed on the control supports. A similar capacity was also found for both oligosorbents. However, the immobilization by covalent bonding appeared more robust for the determination of OTA in the wine. A conventional sorbent and an immunoaffinity column were also applied to the determination of OTA in red wine to compare the potential of the various approaches for the treatment of such complex samples.

Abstract
High-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI-MS-MS) is regarded as one of the most powerful techniques for separation and identification of proteins. Recently, much effort has been made to improve the separation capacity, detection sensitivity, and analysis throughput of micro- and nano-HPLC, by increasing column length, reducing column internal diameter, and using integrated techniques. Development of HPLC columns has also been rapid, as a result of the use of submicrometer packing materials and monolithic columns. All these innovations result in clearly improved performance of micro- and nano-HPLC for proteome research.

Abstract
A complete characterization is presented of a highly selective solid-phase extraction (SPE) sorbent which exploits the properties of aptamers. An oligosorbent based on aptamers immobilized on a solid support was synthesized and tested for the selective extraction of cocaine from human plasma. Anticocaine aptamers were immobilized to CNBr-activated Sepharose, and an extraction procedure was developed in pure media. Specific retention of cocaine on the oligosorbent was demonstrated, and the capacity of the support was determined. This oligosorbent was then applied to the selective extraction of cocaine from plasma at a concentration of 0.4 mg L(-1), i.e., corresponding to the plasma concentration reached after an intake of a single dose of cocaine. Extraction recovery close to 90% was obtained. Moreover, interfering compounds that perturbed cocaine quantification when using a standard SPE sorbent were not retained on the oligosorbent, thus allowing fast and reliable analyses of plasma samples with an estimated limit of detection of 0.1 microg mL(-1).
