Immunology Consultants Recombinant Hamster (CHO) Annexin A5, 0.025 mg
Supplier: Immunology Consultants AG65042501Z
Recombinant CHO Annexin A5 (ANXA5; GenBank XP_027247784.1) is expressed in CHO‑S cells with a 6xHIS tag and purified by nickel affinity chromatography to >90% purity. The protein appears at ~40 kDa under reducing conditions and is quantified by Bradford assay. Annexin A5 is a highly immunogenic CHO host cell protein that can accumulate during cell culture and co‑purify with therapeutic proteins, posing potential safety risks if not effectively removed. This high‑quality recombinant antigen provides a reliable standard for ELISA development, HCP assay calibration, and impurity profiling. Its CHO‑derived structure ensures biological relevance for evaluating immunogenicity risks and refining purification strategies. An excellent choice for teams developing targeted detection tools or monitoring ANXA5‑related impurities in biologics manufacturing.
