Lysosomal Protective Protein (Host Cell Protein) ELISA Kit – CHO (Chinese Hamster Ovary)

The Lysosomal Protective Protein / Cathepsin A (Host Cell Protein) ELISA Kit – CHO (Chinese Hamster Ovary) is a highly sensitive two-site immunoassay designed to detect CTSA, a lysosomal enzyme involved in protein degradation, cellular homeostasis, and lysosomal function. CTSA is a host cell protein (HCP) released during CHO cell culture and can impact the safety and stability of biopharmaceutical products if not adequately removed.
