Introduction
Complement Factor B, also known as CFB, encodes complement factor B which is a component of the alternative pathway of complement activation. Factor B circulates in the blood as a single chain polypeptide. Once the alternative pathway is activated 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 connects with C3b to form the alternative pathway C3 convertase. Also, Bb is involved in the proliferation of preactivated B lymphocytes, while Ba inhibits their proliferation.
Description
CFB Human Recombinant produced in Sf9 Baculovirus cells is
a single, glycosylated polypeptide chain containing 245 amino acids (26-259a.a.)
and having a molecular mass of 27.3kDa (Molecular size on SDS-PAGE will appear
at approximately 28-40 kDa). CFB is expressed with a 11 amino acid His tag at
C-Terminus and purified by proprietary chromatographic techniques.
Source
Sf9, Baculovirus cells.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
CFB protein solution (0.5mg/ml) contains Phosphate
Buffered Saline (pH 7.4) and 10% glycerol.
