Human complement component C3.

Recognizes a C3a-determinant (C3 alpha-chain) which is present also on native C3. Allows discrimination of ubiquitous or nonspecifically bound native C3 from biologically active C3b fragment, C3b or C are negative with this clone. The antibody inhibits the anaphylactic function of C3a: the capacity of C3a to induce serotonin release from thrombocytes in vitro is inhibited; similarly, treatment of C3a with the antibody inhibits the C3a-induced skin reaction in vivo. Species cross-reactivity: Guinea pig and rabbit C3/C3a.

• IHC
• IHC - Frozen
• Western blot

Suitable for use in Immunohistochemistry (frozen sections) and Western blotting. The antibody is, in combination with antibodies to the C3b fragment, an excellent control for distinguishing ubiquitous or nonspecifically bound native C3 from the biologically active C3 fragment. Nonactivated C3 still bears the C3a determinant, whereas activated C3 (C3b, C3d) is C3a-negative. It is therefore useful for immunopathological assays (demonstration of C3 deposition in biopsies) and for C3a assays research purposes.
