C3 is the most abundant complement protein in rat serum.
Its biological function strongly resembles that of C3 in man and other laboratory animal species.
It has a central role in the activation system being common to both pathways.
Activation of C3 is achieved by very specific limited proteolysis resulting in the release of a number of degradation fragments.
The anaphylotoxin C3a promotes smooth muscle contraction and increases vascularpermeability: the large C3b fragment is involved in binding to the complement activator and can be interact with specific receptors to allow efficient clearance of the activating cell or particle; degradation fragments of C3b (C3bi, C3c, C3dg C3d) are important in receptor binding and clearance mechanisms, in virus neutralization and possibly in the immune response
The monoclonal antibody is raised against C3c, which is the major fragment resulting from C3 cleavage by C3 convertase and factor I.
It is composed of an intact beta chain bound to two fragments of the alpha chain.

Host：goat
Source Antibody：rat
Grade：Purified
Purity：Purified
Form：Supplied as a lyophilized powder from PBS, pH 7.2. No preservatives added. Labeled with Fluorescein isothiocyanate (FITC). Reconstitute in 1ml sterile ddH2O. Dilute further in PBS, pH 7.2.
Specificity：Recognizes rat C3, C3c. In immunoelectrophoresis against fresh rat serum, a single precipitin line is obtained in the beta-1 region representing native C3. Against serum containing partly activated C3, a precipitin line is obtained which extends from the beta-1 into the alpha-2 region, demonstrating a gradient. In old serum containing totally activated C3 a single precipitin line in the alpha-2 region is obtained. Also reacts with the fragments C3b, C3bi and smaller fragments, since they all carry antigenic determinants of the C3c domain. Does not react with any other proteins component of rat serum or plasma.
