CFB (260-764) Human, Sf9

Source: Sf9, Baculovirus cells.Sterile Filtered colorless solution.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 lymphocytesâ€TM proliferation. The gene that codes for this protein is located on chromosome six.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.
