C4a is produced during activation of both lectin and the classical pathways of complement. C4a is a non glycosylated polypeptide containing 77 amino acids. C4a is a member of the anaphylatoxin family of 3 proteins (C3a, C4a and C5a) produced by the activation of complement.\u003c\/p\u003e\n\u003ch3\u003eProduct format\u003c\/h3\u003e\n\u003cp\u003eProvided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development.
