  • HY-P71718
    C1QA Protein, Mouse (P.pastoris, His)

    C1qaComplement C1q subcomponent subunit A

    Mouse P. pastoris
    The C1QA protein helps form C1, the starting component of the serum complement system. C1q binds to the zymogens C1r and C1s, resulting in C1 assembly. C1QA Protein, Mouse (P.pastoris, His) is the recombinant mouse-derived C1QA protein, expressed by P. pastoris , with N-6*His labeled tag.
  • HY-P72108
    C1QA Protein, Mouse (His-SUMO)

    C1qaComplement C1q subcomponent subunit A

    Mouse E. coli
    The C1QA protein helps form C1, the starting component of the serum complement system. C1q binds to the zymogens C1r and C1s, resulting in C1 assembly. C1QA Protein, Mouse (His-SUMO) is the recombinant mouse-derived C1QA protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
  • HY-P75464
    C1QB Protein, Human (sf9, His)

    Complement C1q subcomponent subunit B; C1QB

    Human Sf9 insect cells
    The C1QB protein plays a critical role in the assembly of C1, the initial component of the serum complement system. C1q binds to the zymogens C1r and C1s, resulting in C1 assembly. C1QB Protein, Human (sf9, His) is the recombinant human-derived C1QB protein, expressed by Sf9 insect cells , with C-His labeled tag.
  • 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.
  • 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.
