Introduction

Factor B is a protein, build from a single chain that circulates in the blood. Complement factor D cleaves and activates factor B, thus creating a catalytic subunit Bb and noncatalytic chain Ba. Subunit Bb is a serine protease that can bind to C3b and forms alternative pathway C3 convertase. Subunit Ba acts as an inhibitor for proliferation of lymphocytes, when Bb is part of the lymphocytes’ proliferation. The gene that codes for this protein is located on chromosome six.

Description

CFB Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 514 amino acids (260-764 a.a) and having a molecular mass of 58.1kDa.
CFB is fused to an 9 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques.

Source

Sf9, Baculovirus cells.
