Screening and validation of an alkaline-tolerant biomimetic affinity chromatography A5-87 resin for purification of discarded bovine serum Immunoglobulin G. J Chromatogr A 2024; 1714:464580.

Abstract
It is important to recycle the bovine blood discarded at slaughter and develop it into high value-added bovine serum products. Biomimetic affinity chromatography (BiAC) resins have been developed to specifically purify bovine serum immunoglobulin G (Bs-IgG). The BiAC strategy was used to screen the resins with the best purification effect on Bs-IgG. Four resins with specificity for Bs-IgG adsorption were selected from 90 BiAC resins. Finally, BiAC-A5-87 was selected and used to purify Bs-IgG based on the results of SDS-PAGE and BCA protein quantification analysis. The adsorption capacity and purity of BiAC-A5-87 were 32.79 ± 3.57 mg/mL and 85.9 ± 1.21 % for Bs-IgG, respectively. The total protein recovery rate of Bs-IgG purified by BiAC-A5-87 was 89.78±3.52 %. The resin of BiAC-A5-87 column was recycled in 40 breakthrough cycles, and its Bs-IgG adsorption efficiency decreased by less than 10 %. After soaking BiAC-A5-87 in 1.0 moL NaOH solution for 64 h, its adsorption capacity for Bs-IgG was almost the same as that before soaking. The development of waste bovine serum not only realizes the utilization of blood resources and produces high economic benefits but also reduces the pollution of the environment.

Abstract
To rapidly find “best-in-class” antibody therapeutics, it has become essential to develop high throughput (HTP) processes that allow rapid assessment of antibodies for functional and molecular properties. Consequently, it is critical to have access to sufficient amounts of high quality antibody, to carry out accurate and quantitative characterization. We have developed automated workflows using liquid handling systems to conduct affinity-based purification either in batch or tip column mode. Here, we demonstrate the capability to purify >2000 antibodies per day from microscale (1 mL) cultures. Our optimized, automated process for human IgG1 purification using MabSelect SuRe resin achieves ∼70% recovery over a wide range of antibody loads, up to 500 µg. This HTP process works well for hybridoma-derived antibodies that can be purified by MabSelect SuRe resin. For rat IgG2a, which is often encountered in hybridoma cultures and is challenging to purify via an HTP process, we established automated purification with GammaBind Plus resin. Using these HTP purification processes, we can efficiently recover sufficient amounts of antibodies from mammalian transient or hybridoma cultures with quality comparable to conventional column purification.

Abstract
Antibodies continue to be extremely utilized entities in myriad applications including basic research, imaging, targeted delivery, chromatography, diagnostics, and therapeutics. At production stage, antibodies are generally present in complex matrices and most of their intended applications necessitate purification. Antibody purification has always been a major bottleneck in downstream processing of antibodies, due to the need of high quality products and associated high costs. Over the years, extensive research has focused on finding better purification methodologies to overcome this holdup. Among a plethora of different techniques, affinity chromatography is one of the most selective, rapid and easy method for antibody purification. This review aims to provide a detailed overview on affinity chromatography and the components involved in purification. An array of support matrices along with various classes of affinity ligands detailing their underlying working principles, together with the advantages and limitations of each system in purifying different types of antibodies, accompanying recent developments and important practical methodological considerations to optimize purification procedure are discussed.
