  • HY-P700696
    C1s/Complement component C1s Protein, Human (HEK293, His)

    Complement C1s subcomponent; C1 esterase;

    		Human HEK293
    C1s/Complement component C1s, a serine protease and B chain, forms C1 with C1q and C1r, initiating the classical complement pathway. Activated by C1r, C1s then activates downstream components C2 and C4, crucially driving the complement system cascade. C1s/Complement component C1s Protein, Human (HEK293, His) is the recombinant human-derived C1s/Complement component C1s protein, expressed by HEK293, with C-His labeled tag. The total length of C1s/Complement component C1s Protein, Human (HEK293, His) is 673 a.a., with molecular weight of 55-60 kDa (light chain), 32-35 kDa (heavy chain).
  • HY-P75463
    C1s-A subcomponent Protein, Mouse (HEK293, His)

    Complement C1s-A subcomponent; C1 esterase; C1sa; C1s

    		Mouse HEK293
    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. The total length of C1s-A subcomponent Protein, Mouse (HEK293, His) is 673 a.a., with molecular weight of ~76.6 kDa.
