Immunology Consultants Hamster (CHO) Cathepsin B - Recombinant, 0.025mg
SDP

Catalog No. 5000435354
Encompass_Preferred

Recombinant CHO Cathepsin B (CTSB; UniProt G3H0L9) is expressed in CHO cells with a 6xHIS tag and purified to >95% purity. The protein appears at ~45 kDa under reducing conditions and is quantified by A280. Cathepsin B is a dual‑function cysteine protease with both endopeptidase and carboxypeptidase activity, making it a significant CHO‑derived impurity capable of fragmenting therapeutic proteins. Its presence has been linked to antibody degradation in bioprocessing. This high‑quality recombinant antigen provides a reliable standard for ELISA development, antibody generation, and impurity profiling. Its CHO‑derived structure ensures biological relevance for protease‑risk evaluation and purification optimization. A strong choice for teams developing targeted HCP detection tools or assessing protease‑driven degradation.
