Properdin Recombinant Protein

Properdin is also known as Complement factor P, CFP, PFC, a positive regulator of the alternate pathway of complement. It binds to and stabilizes the C3- and C5-convertase enzyme complexes. Properdin is produced by many different leukocyte subsets and circulates as cyclic oligomers of monomeric subunits. Properdin on platelet/granulocyte aggregates (PGA) formation are tightly regulated by Factor H, properdin enhances PGA formation via increased production of C5a, and that inhibition of properdin function has therapeutic potential to limit thromboinflammation in diseases characterized by increased PGA formation.

Lyophilized Protein should be stored at -20˚ C or lower for long term storage. Upon reconstitution, working aliquots should be stored at -20˚ C or -70˚ C. Avoid repeated freeze-thaw cycles.

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 50.7 kDa. The protein migrates as 55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
