Main characteristics Protein binding capacity: 16.5 mg/mL Biotin Affinity Purification We offer a variety of resins for the purification of biotinylated or desthiobiotinylated proteins, peptides, and other molecules. By using affinity chromatography, one can separate proteins that bind to a certain fragment from proteins that do not bind that specific fragment. Because this technique of purification relies on the biological properties of the protein needed, it is a useful technique and proteins can be purified many folds in one step. Affinity chromatography is a suitable initial purification step for purifying solubilized recombinant proteins that contain relevant tags; however, unwanted proteins are likely to also bind to the affinity resin column and will elute in the final wash along with the desired protein of interest. Additional columns can give additional flexibility for elution and regeneration times, at the cost of additional equipment and resin costs. Affinity chromatography can be used in a number of applications, including nucleic acid purification, protein purification from cell free extracts, and purification from blood.
