Native Human Complement C3c

• Cat.No.: C3-194H

Specification

• Species: Human
• Source: Human Plasma
• Tag: Non
• Description: Complement C3 (C3) is the most abundant component of the complement system, with levels in human plasma of ~1.2-1.5 mg/ml. It is central to the activation of both the classical and alternative complement pathways, both of which lead to the proteolytic processing of C3 to C3a and C3b. C3 exists as a heterodimer with molecular masses of 115 kDa and 75 kDa, although it is readily processed to smaller fragments (C3a, C3b, C3c) as evidenced by the molecular weight description below. The current protocol yields C3c, however intact C3 and/or partially processed C3a/C3b may potentially be purified if certain precautions are taken during processing (ie, processing at 4°C, protease inhibitors throughout processing).
