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.\u003c\/p\u003e\n\u003ch3\u003eProduct format\u003c\/h3\u003e\n\u003cp\u003eProvided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development.
