Porfirio MCP, Santos JB, Alves AN, Santos LS, Bonomo RCF, da Costa Ilhéu Fontan R. Purification of pineapple bromelain by IMAC chromatography using chlorophyll-activated macroporous matrices. J Chromatogr B Analyt Technol Biomed Life Sci 2024; 1234:124027. [PMID: 38320436 DOI: 10.1016/j.jchromb.2024.124027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 01/08/2024] [Accepted: 01/20/2024] [Indexed: 02/08/2024]
Abstract
This study investigated the purification of bromelain obtained from pineapple fruit using a new adsorbent for immobilized metal ion affinity chromatography (IMAC), with chlorophyll obtained from plant leaves as a chelating agent. The purification of bromelain was evaluated in batches from the crude extract of pineapple pulp (EXT), and the extract precipitated with 50 % ammonium sulfate (EXT.PR), the imidazole buffer (200 mM, pH 7.2) being analyzed and sodium acetate buffer, pH 5.0 + 1.0 NaCl as elution solutions. All methods tested could separate forms of bromelain with molecular weights between ±21 to 25 kDa. Although the technique using EXT.PR stood out in terms of purity, presenting a purification factor of around 3.09 ± 0.31 for elution with imidazole and 4.23 ± 0.12 for acetate buffer solution. In contrast, the EXT methods obtained values between 2.44 ± 0.23 and 3.21 ± 0.74 for elution with imidazole and acetate buffer, respectively, for purification from EXT.PR has lower yield values (around 5 %) than EXT (around 15 %). The number of steps tends to reduce yield and increase process costs, so the purification process in a monolithic bed coupled to the chromatographic system using the crude extract was evaluated. The final product obtained had a purification factor of 6, with a specific enzymatic activity of 59.61 ± 0.00 U·mg-1 and a yield of around 39 %, with only one band observed in the SDS-PAGE electrophoresis analysis, indicating that the matrix produced can separate specific proteins from the total fraction in the raw material. The IMAC matrix immobilized with chlorophyll proved promising and viable for application in protease purification processes.

Aparna GM, Tetala KKR. Titanium particles incorporated polymer monolith microcolumn for phosphoprotein enrichment from biological samples. J Pharm Biomed Anal 2023; 233:115453. [PMID: 37224729 DOI: 10.1016/j.jpba.2023.115453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 04/28/2023] [Accepted: 05/09/2023] [Indexed: 05/26/2023]
Abstract
In proteomic studies, selective enrichment of target phosphoproteins from biological samples is of importance. Of various enrichment methods, affinity chromatography is widely preferred method. Development of micro-affinity columns with simple strategies are in constant demand. Here in this report, for the first time, we have embedded TiO2 particles within the monolith structure in a single step. Fourier transform infrared spectroscopy and scanning electron microscope analysis has confirmed the successful incorporation of TiO2 particles within the polymer monolith. Incorporation of 3-(trimethoxy silyl) propyl methacrylate within the poly(hydroxyethyl methacrylate) based monolith composition has enhanced its rigidity and one fold phosphoprotein (α-casein) adsorption capacity. Presence of only 66.6 µg of TiO2 particles within the monolith has displayed a four-fold higher affinity to α-casein over the non-phosphoprotein i.e. bovine serum albumin. Under optimized conditions (TiO2 particle and acrylate silane), the affinity monolith has a maximum adsorption capacity of ∼ 72 mg per gram monolith. Translation of TiO2 particles-monolith into a microcolumn of 3 cm long and 19 µL volume was successful. α-casein was selectively separated from an artificial protein mixture of α-casein and BSA, α-casein spiked human plasma, and cow milk within 7 min.

Highly selective titanium (IV)-immobilized O-Phospho-L-tyrosine modified magnetic nanoparticles for the enrichment of intact phosphoproteins. J Sep Sci 2022; 45:3054-3062.

Abstract
Phosphorylation is one of the most important protein post-translational modifications, which possesses dramatic regulatory effects on the function of proteins. In consideration of the low abundance and low stoichiometry of phosphorylation and non-specific signal suppression, efficient capture of the phosphoproteins from complex biological samples is critical to meet the need of protein profiling. In this work, a facile preparation of titanium (IV)-immobilized O-Phospho-L-tyrosine modified magnetic nanoparticles were developed for the enrichment of intact phosphoproteins. The prepared magnetic nanoparticles were characterized by various instruments and had a spherical shape with an average diameter of 300 nm. The adsorption isotherms were investigated and the maximum capacity for β-casein was calculated to be 961.5 mg/g. Standard protein mixtures and biological samples (non-fat milk and human serum) were selected to test the enrichment performance. Sodium dodecyl sulfate-poly acrylamide gel electrophoresis analysis demonstrated the excellent enrichment performance with high selectivity. With the superparamagnetic property, titanium (IV)-immobilized O-Phospho-L-tyrosine modified magnetic nanoparticles were convenient for the practical application and clinical promotion, thus having a promising prospect in the field of phosphoprotein research.

Abstract
Mas-related G protein-coupled receptor X2 (MrgX2) has been identified to be critical in drug-induced pseudo-allergic reactions and allergic diseases. Herein, an affinity high-performance liquid chromatography was established for the specific detection and enrichment of MrgX2. Substance P was used as an affinity ligand and immobilized on a glutaraldehyde-modified amino silica gel. The successful grafting of substance P was characterized by infrared spectroscopy, elemental analysis, X-ray photoelectron spectroscopy, thermogravimetric analysis, and nitrogen adsorption and desorption analyzes. The prepared materials were then used as the stationary phase to investigate the retention behavior of MrgX2 recombinant protein on the affinity column. The results obtained with the analytical techniques show the specificity and selectivity of the MrgX2 recombinant protein on the affinity column. The repeatability and reproducibility for the analysis of MrgX2 on the NH2-Silico@GD@SP column show relative standard deviation (RSD) values lower than the acceptance criteria of 2 and 5% of retention time, and RSD of peak areas < 7%. The RSD value of the results obtained for the control of the activity of the prepared columns respond to the acceptance criteria of 5% and proves that the NH2-Silico@GD@SP column are stable until 48 h. The suitability of the NH2-Silico@GD@SP column offline SEC system has been tested by using MrgX2 as positive control. The results of this experiment indicate that the offline system may be used to analyze the retention fraction. MrgX2 extracted from human mast cells LAD2 was also verified. An obvious retention can be observed and the natural MrgX2 was concentrated 114.6 times compared with the original complex components by using the affinity column. These results may provide a new approach for the specific detection and enrichment of G-protein-coupled receptors.

Abstract
Selective separation and enrichment of phosphoproteins possess the distinct clinical and biological importance in the diagnosis, treatment, and management of several fatal human diseases. In this study, a facile synthesis of titanium(IV) ion-immobilized arsenate-modified poly(glycidyl methacrylate) microparticles (denoted as Ti4+-arsenate-PGMA-MPs) was developed for the efficient enrichment of intact phosphoproteins found in biologically complex protein samples. By virtue of the strong interaction between the titanium ions immobilized on the surface of Ti4+-arsenate-PGMA-MPs and phosphate groups of phosphoproteins, Ti4+-arsenate-PGMA-MPs had a high saturated adsorption capacity for phosphoproteins (901 mg/g for β-casein), which was much higher than that of non-phosphoproteins (73.5 mg/g for BSA). Ti4+-arsenate-PGMA-MPs were characterized by SEM, TEM, and FT-IR, and the average particle diameter was about 2.5 μm with good dispersibility. Besides, the application of Ti4+-arsenate-PGMA-MPs in real biological samples was investigated by SDS-PAGE analysis, and the results showed that Ti4+-arsenate-PGMA-MPs were able to enrich phosphoproteins efficiently.

Abstract
Affinity membrane is widely employed to promote specific adsorption of toxins and reduce the blood purification therapeutic time. However, it suffers from insufficient toxin binding and low hemocompatibility. Herein, a novel anticoagulant affinity membrane (AAM) was developed to clear bilirubin from human blood in a pore-flow-through way. Firstly, a nylon net membrane with a regularly arranged pore as the matrix was coated with poly(pyrrole-3-carboxylic acid) via chemical vapor deposition (CVD) method. Then, poly(L-arginine) (PLA) as a highly specific ligand of bilirubin, was immobilized onto the surface of the composited membrane after the modification of heparin. Owing to the 3-dimensional molecular architecture of PLA, up to 86.1 % of bilirubin was efficiently cleared. Besides, the AAM exhibited effective anticoagulant activity in the measurement of clotting time, with suppressed thrombus formation, low hemolysis ratio, minimized platelet and leukocyte adhesion, and excellent biosafety. Therefore, the AAM has enormous potential in blood purification therapy for enhancing hemocompatibility and bilirubin removal.
