Anti-Complement C3b-iC3b [7C12] Antibody

This mouse IgG1 antibody was generated against human C3b and iC3b bound to a carbohydrate matrix via the alternative pathway of complement activation and recognizes human C3, C3b and iC3b and cross reacts with primate but not non-primate (guinea pig, horse, dog) homologs.

The complement system consists of a number of small proteins found in the blood, generally synthesized by the liver, and normally circulating as inactive precursors (pro-proteins). When stimulated by one of several triggers, proteases in the system cleave specific proteins to release cytokines and initiate an amplifying cascade of further cleavages. The end-result of this activation cascade is massive amplification of the response and activation of the cell-killing membrane attack complex.

Complement component 3 (C3) plays a central role in the activation of the complement system. C3 cleavage by C3-convertase produces C3b and iC3b. C3b leads to an inflamatory response and also covalently binds to microbial cell surfaces aiding in opsonization of the microbe.

Data

A: Binding of three different nSI-labelled MAbs to C3b(i)-Sepharose prepared with human serum, and to putative C3b(i)-Sepharose samples prepared with the sera of other primates (cynomologous monkey, rhesus monkey, and baboon) and non-primates (guinea pig, horse, and dog). The total cpm input was circa 40000 for each MAb. Other non-primate samples tested, which also showed a lack of binding, were cat, sheep, and cow. B: inhibition of binding of the same 125I-labelled MAbs to human C3b(i)-Sepharose, by zymosan-treated sera (Mollnes and Lachmarm, 1987) of the same species tested in A. MAb 8Ell consistently showed a unique specificity since it was the only MAb of the three that bound baboon C3b(i)-Sepharose (A), and was inhibited by zymosan-treated baboon serum.
