| Cat. No. : |
C2-598H |
| Description : |
Complement component C2 is part of the classical complement pathway which plays a major role in innate immunity against infection. C2 is a glycoprotein synthesized in liver hepatocytes and several other cell types in extrahepatic tissues. This pathway is triggered by a multimolecular complex C1, and subsequently the single-chain form of C2 is cleaved into two chains referred to C2a and C2b by activated C1. C2a containing a serine protease domain combines with complement component C4b to form the C3 convertase C4b2a which is responsible for C3 activation, and leads to the stimulation of adaptive immune responses via Lectin pathway. Deficiency of C2 (C2D) is the most common genetic deficiency of the complement system, and two types of C2D have been recognized in the context of specific MHC haplotypes. C2D in human is reported to increase susceptibility to infection, and is associated with certain autoimmune diseases, such as rheumatological disorders. |
| Molecular Mass : |
The single-chain form of recombinant human complement component C2 comprises 743 amino acids and has a calculated molecular mass of 82.5kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhC2 is 90-100 kDa as a result of glycosylation. |
