Purified Complement Proteins

Product name

C8 Protein

Purified human complement component C8

Intended use

Complement component C8 is unique to the terminal complement pathway. It is composed of three protein chains (a, 65 KD; ß, 65 KD;, Γ 22 KD) and is present in plasma at approximately 55 mg/L. Together with the other proteins of the terminal pathway, C8 forms the membrane attack complex or MAC.

Concentration: 1.0 mg/ml
