Recombinant Human CFB protein, His-tagged

Cat.No.: CFB-141H
Product Overview: Recombinant Human CFB(26-259aa) fused with His tag at C-terminal was expressed in Insect cells.
Description: CFB, also known as complement factor B, is 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.
