Anti-Complement component C3 (alpha chain, anaphylatoxin), clone 6B1

Protein function: C3 plays a central role in the activation of the complement system. Its processing by C3 convertase is the central reaction in both classical and alternative complement pathways. After activation C3b can bind covalently, via its reactive thioester, to cell surface carbohydrates or immune aggregates. [The UniProt Consortium]
