A rabbit antiserum raised against human complement C3a protein.

C3a, along with C3b, is a cleavage product of complement protein C3. C3a is a anaphylatoxin that binds to the C3aR receptor. This induces T-cell activation, angiogenesis stimulation, chemotaxis, mast cell degranulation, and macrophage activation.

Quidel's polyclonal antiserum to C3a can been used in a variety of immunochemical techniques including RID, EIA, Ouchterlony.
