Recombinant human CFB-Bb, His-tagged

Cat.No.: CFB-Bb-2479H
Product Overview: Recombinant human CFB-Bb protein, fused to His-tag at N-terminus, was expressed in E.coli.
Description: CFB encodes complement factor B, a component of the alternative pathway of complement activation. Factor B circulates in the blood as a single chain polypeptide. Upon activation of the alternative pathway, it is cleaved by complement factor D yielding the noncatalytic chain Ba and the catalytic subunit Bb. The active subunit Bb is a serine protease which associates with C3b to form the alternative pathway C3 convertase. Bb is involved in the proliferation of preactivated B lymphocytes, while Ba inhibits their proliferation.
