Active Human C3 Reference Standard

• Cat.No.: C3-7H

Specification

• Description: The C3c component is central in both complementactivation pathways, with different specific proteolytic systems cleaving itto form C3 convertase. Cleavage of C3 releases C3a and the Cab fragment whichis part of the alternative C3 convertase. C3 levels can be low because ofdecreased synthesis or due to consumption. High C3 levels are seen in highlyacute or chronic inflammation, hepatic cholestasis and during the thirdtrimester of pregnancy. Unwanted complement activation is a major cause oftissue damage in various pathological conditions and contributes to quite afew immune complex diseases.
• Species: Human
