Abstract
The emergence of thrombopoietin mimetic peptides presents a promising therapeutic strategy for addressing thrombocytopenia. This particular study aimed to establish a direct, expeditious, and efficient method for modifying and purifying a novel thrombopoietin mimetic peptide. Precursor proteins were subjected to modification utilizing three distinct fatty acids: C25H42O7N2, C39H66O15N4, and C41H70O15N4. Liquid chromatography analyses demonstrated that C41H70O15N4 yielded the most effective modification results. Mass spectrometry findings validated the correspondence between the theoretical and actual molecular weights of each sample. In vivo experiments conducted on normal mice showcased that the C41H70O15N4 modification group exhibited the highest platelet count, peaking at an impressive 5047 × 109/L. This count was approximately twice that of the peak platelet count observed in the dTMP group and four times higher than the control group. Pharmacokinetic investigations revealed that the C41H70O15N4 modification group displayed the lengthiest half-life among beagles, persisting for 128.5 h. This duration was approximately 28.5 times longer than that of the unmodified dTMP group. These findings underscore the effectiveness of the established C41H70O15N4 modification and purification method in preserving the biological activity of the thrombopoietin mimetic peptide. The novel thrombopoietin mimetic peptide showcased notable attributes of simplicity and cost-effectiveness, while also exhibiting a significant platelet-promoting effect and an extended half-life. Consequently, this novel peptide holds substantial significance for advancing the treatment of thrombocytopenia.

Adaptation of the binding domain of Lactobacillus acidophilus S-layer protein as a molecular tag for affinity chromatography development. Front Microbiol 2023; 14:1210898. [PMID: 37383629 PMCID: PMC10293925 DOI: 10.3389/fmicb.2023.1210898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 05/19/2023] [Indexed: 06/30/2023] Open
Abstract
Introduction The S-layer proteins are a class of self-assembling proteins that form bi-dimensional lattices named S-Layer on the cell surface of bacteria and archaea. The protein SlpA, which is the major constituent of the Lactobacillus acidophilus S-layer, contains in its C-terminus region (SlpA284 - 444), a protein domain (named here as SLAPTAG) responsible for the association of SlpA to the bacterial surface. SLAPTAG was adapted for the development of a novel affinity chromatography method: the SLAPTAG-based affinity chromatography (SAC). Methods Proteins with different molecular weights or biochemical functions were fused in-frame to the SLAPTAG and efficiently purified by a Bacillus subtilis-derived affinity matrix (named Bio-Matrix or BM). Different binding and elution conditions were evaluated to establish an optimized protocol. Results The binding equilibrium between SLAPTAG and BM was reached after a few minutes of incubation at 4°C, with an apparent dissociation constant (KD) of 4.3μM. A reporter protein (H6-GFP-SLAPTAG) was used to compare SAC protein purification efficiency against commercial immobilized metal affinity chromatography. No differences in protein purification performance were observed between the two methods. The stability and reusability of the BM were evaluated, and it was found that the matrix remained stable for more than a year. BM could be reused up to five times without a significant loss in performance. Additionally, the recovery of bound SLAP-tagged proteins was explored using proteolysis with a SLAP-tagged version of the HRV-3c protease (SLAPASE). This released the untagged GFP while the cut SLAPTAG and the SLAPASE were retained in the BM. As an alternative, iron nanoparticles were linked to the BM, resulting in BMmag. The BMmag was successfully adapted for a magnetic SAC, a technique with potential applications in high-throughput protein production and purification. Discussion The SAC protocol can be adapted as a universal tool for the purification of recombinant proteins. Furthermore, the SAC protocol utilizes simple and low-cost reagents, making it suitable for in-house protein purification systems in laboratories worldwide. This enables the production of pure recombinant proteins for research, diagnosis, and the food industry.

Use of Microfluidic Capillary Electrophoresis for the Determination of Multi-Component Protein Adsorption Isotherms: Application to High-Throughput Analysis for Hydrophobic Interaction Chromatography. Pharmaceutics 2021; 13:pharmaceutics13122135.

Abstract
Chromatography is a widely used separation process for purification of biopharmaceuticals that is able to obtain high purities and concentrations. The phenomena that occur during separation, mass transfer and adsorption are quite complex. To better understand these phenomena and their mechanisms, multi-component adsorption isotherms must be investigated. High-throughput methodologies are a very powerful tool to determine adsorption isotherms and they waste very small amounts of sample and chemicals, but the quantification of component concentrations is a real bottleneck in multi-component isotherm determination. The behavior of bovine serum albumin, Corynebacterium diphtheriae CRM197 protein and lysozyme, selected as model proteins in binary mixtures with hydrophobic resin, is investigated here. In this work we propose a new method for determining multi-component adsorption isotherms using high-throughput experiments with filter plates, by exploiting microfluidic capillary electrophoresis. The precision and accuracy of the microfluidic capillary electrophoresis platform were evaluated in order to assess the procedure; they were both found to be high and the procedure is thus reliable in determining adsorption isotherms for binary mixtures. Multi-component adsorption isotherms were determined with a totally high-throughput procedure that turned out to be a very fast and powerful tool. The same procedure can be applied to every kind of high-throughput screening.

Abstract
This work combines two well-established technologies to generate a breakthrough in protein production and purification. The first is the production of polyhydroxybutyrate (PHB) granules in engineered strains of Escherichia coli. The second is a recently developed group of self-cleaving affinity tags based on protein splicing elements known as inteins. By combining these technologies with a PHB-specific binding protein, a self-contained protein expression and purification system has been developed. In this system, the PHB-binding protein effectively acts as an affinity tag for desired product proteins. The tagged product proteins are expressed in E. coli strains that also produce intracellular PHB granules, where they bind to the granules via the PHB-binding tag. The granules and attached proteins can then be easily recovered following cell lysis by simple mechanical means. Once purified, the product protein is self-cleaved from the granules and released into solution in a substantially purified form. This system has been successfully used at laboratory scale to purify several active test proteins at reasonable yield. By allowing the bacterial cells to effectively produce both the affinity resin and tagged target protein, the cost associated with the purification of recombinant proteins could be greatly reduced. It is expected that this combination of improved economics and simplicity will constitute a significant breakthrough in both large-scale production of purified proteins and enzymes and high-throughput proteomics studies of peptide libraries.
