Abstract
Mass spectrometry-based approaches have enabled important breakthroughs in quantitative proteomics in the last decades. This development is reflected in the better quantitative assessment of protein levels as well as to understand post-translational modifications and protein complexes and networks. Nowadays, the focus of quantitative proteomics shifted from the relative determination of proteins (ie, differential expression between two or more cellular states) to absolute quantity determination, required for a more-thorough characterization of biological models and comprehension of the proteome dynamism, as well as for the search and validation of novel protein biomarkers. However, the physico-chemical environment of the analyte species affects strongly the ionization efficiency in most mass spectrometry (MS) types, which thereby require the use of specially designed standardization approaches to provide absolute quantifications. Most common of such approaches nowadays include (i) the use of stable isotope-labeled peptide standards, isotopologues to the target proteotypic peptides expected after tryptic digestion of the target protein; (ii) use of stable isotope-labeled protein standards to compensate for sample preparation, sample loss, and proteolysis steps; (iii) isobaric reagents, which after fragmentation in the MS/MS analysis provide a final detectable mass shift, can be used to tag both analyte and standard samples; (iv) label-free approaches in which the absolute quantitative data are not obtained through the use of any kind of labeling, but from computational normalization of the raw data and adequate standards; (v) elemental mass spectrometry-based workflows able to provide directly absolute quantification of peptides/proteins that contain an ICP-detectable element. A critical insight from the Analytical Chemistry perspective of the different standardization approaches and their combinations used so far for absolute quantitative MS-based (molecular and elemental) proteomics is provided in this review.

Ratiometric quantification of β2-microglobulin antigen in human serum based on elemental labeling strategy. Talanta 2018; 189:249-253. [PMID: 30086914 DOI: 10.1016/j.talanta.2018.07.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2018] [Revised: 06/22/2018] [Accepted: 07/01/2018] [Indexed: 11/23/2022]
Abstract
Ratiometric quantification for competitive immunoassay based on internal standard element detection utilizing inductively coupled plasma mass spectrometry (ICP-MS) as multiplex readout has been demonstrated. The Beta-2-microglobulin (β2-MG) associated with clinical diseases was detected by Y-labeled capture antibody used as internal standard probes and Sm-labeled antigen used as report probes via antigen-antibody reaction. The ratiometric quantification was achieved by taking the signal ratio of Sm/Y. The ratiometric method could compensate for the particle loss and suppress the signal fluctuation, which improved the precision of the quantitative result. Under the optimized conditions, the calibration curves for β2-MG antigen was linear in the range of 0.25-8.0 μg/mL with a detection limit of 0.17 μg/mL (3σ, n = 11). The recoveries of 96.5%-132% were obtained for serum samples spiked with different concentration standards, and the relative standard deviation (RSD) was less than 10%. The β2-MG results in serum samples obtained by the proposed method correlated well with those obtained by time-resolved fluorescence immunoassay (r = 0.947). This proposed method provides a simpler labeling strategy for ratiometric quantification of immunoassay.

Abstract
The last 10 years witnessed the emerging and growing up of inductively coupled plasma mass spectrometry (ICPMS)-based immunoassay. Its high sensitivity and multiplex potential have made ICPMS a revolutionary technique for bioanalyte quantification after element-tagged immunoassay. This review focuses on the major developments and the applications of ICPMS-based immunoassay, with emphasis on methodological innovations. The ICPMS-based immunoassay with elemental tags of metal ions, nanoparticles, and metal containing polymers was discussed in detail. The recent development of multiplex assay, mass cytometry, suspension array, and surface analysis demonstrated the versatility and great potential of this technique. ICPMS-based immunoassay has become one of the key methods in bioanalysis.

Abstract
Metal-Coded Affinity Tags (MeCAT) reagents were devised for the absolute quantification of labeled proteins and peptides using inductively coupled plasma mass spectrometry (ICP-MS). After the recent publication of quantification approaches for digested proteins, this work presents a multidimensional strategy for the application of MeCAT to samples which require higher chromatographic resolution. Two-dimensional separations based on strong cation exchange (SCX) and reversed-phase (RP) chromatography, were used for the quantification of lysozyme, bovine serum albumin and transferrin after tryptic digestion. The elution protocols were optimized to improve the resolution of the MeCAT-labeled peptides which led to faster elutions in SCX and longer retention times in RP compared with unlabeled peptides. The optimized method provided enough resolution for the samples analyzed. Peptides losses during the whole procedure were studied. Although recoveries of greater than 90% were found in the RP dimension, important global losses in the two-dimensional offline approach forced us to use specific internal standards, in this case MeCAT-labeled standard peptides. External calibration and label-specific isotope dilution analysis (IDA) were tested and compared as possible quantification techniques. While both techniques showed accurate and precise determinations, the label-specific IDA technique resulted in more straightforward measurements and more affordable external calibrations. Finally, simultaneous quantification of three different samples labeled with different lanthanides was successfully performed demonstrating the potential of MeCAT combined with ICP-MS for multiplexing. Electrospray ionization mass spectrometry techniques provided the structural information needed for the identification of the labeled species.

Abstract
An accurate, simple, and sensitive method for the direct determination of proteins by nonspecies specific isotope dilution and external calibration high-performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICPMS) is described. The labeling of myoglobin (17 kDa), transferrin (77 kDa), and thyroglobulin (670 kDa) proteins was accomplished in a single-step reaction with a commercially available bis(2,2'-bipyridine)-4'-methyl-4-carboxybipyridine-ruthenium N-succinimidyl ester-bis(hexafluorophosphate) (Ru-NHS ester). Using excess amounts of Ru-NHS ester compared to the protein concentration at optimized labeling conditions, constant ratios for Ru to proteins were obtained. Bioconjugate solutions containing both labeled and unlabeled proteins as well as excess Ru-NHS ester reagent were injected onto a size exclusion HPLC column for separation and ICPMS detection without any further treatment. A (99)Ru enriched spike was used for nonspecies specific ID calibration. The accuracy of the method was confirmed at various concentration levels. An average recovery of 100% ± 3% (1 standard deviation (SD), n = 9) was obtained with a typical precision of better than 5% RSD at 100 μg mL(-1) for nonspecies specific ID. Detection limits (3SD) of 1.6, 3.2, and 7.0 fmol estimated from three procedure blanks were obtained for myoglobin, transferrin, and thyroglobulin, respectively. These detection limits are suitable for the direct determination of intact proteins at trace levels. For simplicity, external calibration was also tested. Good linear correlation coefficients, 0.9901, 0.9921, and 0.9980 for myoglobin, transferrin, and thyroglobulin, respectively, were obtained. The measured concentrations of proteins in a solution were in good agreement with their volumetrically prepared values. To the best of our knowledge, this is the first application of nonspecies specific ID for the accurate and direct determination of proteins using a Ru-NHS ester labeling reagent.
