Product Name :
C4BPB polyclonal antibody Background :
Complement component 4-binding protein (C4BP) is a plasma glycoprotein that inhibits the classical pathway of complement activation, which is mediated through antibody targeting of foreign antigen. Structurally, C4BP is a disulfide linked, multimeric protein that is composed of seven α chains and one β chain. C4BP functions as a cofactor for C3β inactivator in the cleavage of C3β, and accelerates the decay of C4βC2α (C3 convertase) by acting as a cofactor in the cleavage of C4β by factor I. Streptococcal strains that express Ig-binding cell surface molecules, which are members of the M protein family,can bind to overlapping C4β binding sites in C4BP and therefore, interfere with the classical pathway of complement activation. Bacteria-bound C4BP may be an evolved mechanism that downregulates complement activation in the bacterial host microenvironment, thereby reducing the occurances of bacterial opsonization and phagocytosis.

Describe :

Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. This mechanism is useful when non-specific binding is an issue, for example, in Western blotting (WB) and Immunohistochemistry (IHC). By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific; Specific binding will be absent from the western blot or IHC performed with the neutralized antibody.
