SKU:: 218028
Molecular Weight:: 59.4
Purity:: ≥85% (SDS-PAGE)
Storage Conditions:: -20°C
Supplier:: United States Biological
Format:: Supplied as a liquid in 20mM Tris-HCl, pH 8.0, 0.4M urea, 10% glycerol.
Extra Details:: CFB encodes complement factor B, 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. Source: Recombinant corresponding to aa260-764 from human CFB-Bb protein, fused to His-tag at N-terminus, expressed in E.coli. Molecular Weight: ~59.4kD (528aa) Applications: Suitable for use in SDS-PAGE. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
