Purity: > 90% by SDS - PAGE Format: Liquid. In Phosphate Buffered Saline (pH 7.4) containing 10% glycerol.. SERPINC1, also known as antithrombin-III, is a member of the Serpin superfamily of the serine protease inhibitors. It is the principal plasma Serpin of blood clotting proteases and inhibits thrombin as well as several factors such as Xa. It is one of the most important coagulation inhibitors and is the basic enzyme for the therapeutic action of heparin. In common with SerpinA5 and D1, the inhibitory activity of SerpinC1 dramatically increases the presence of heparin and other glycosaminoglycans. It mediates the promotion of prostaglandin release, inhibitors of leukocyte activation and down-regulation of many inflammatory cytokines. This protein has anti-inflammatory properties besides anticoagulant. Recombinant human SERPINC1, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
