Description
C1s-A subcomponent protein, a serine protease, is pivotal in the classical complement system pathway. Partnering with C1q and C1r, it forms C1, initiating complement activation. Activated by C1r, C1s can subsequently trigger downstream components C2 and C4, influencing the complement system cascade. C1s-A subcomponent Protein, Mouse (HEK293, His) is the recombinant mouse-derived C1s-A subcomponent protein, expressed by HEK293, with C-His labeled tag
