Recombinant Human CFHR1 Protein (His Tag)

Complement Factor H-Related 1 (CFHR1) is a 43 kDa secreted member of the factor H family of glycoproteins. The human Complement Factor H protein family consists of the complement and immune regulators factor H; the factor H-like protein 1 (FHL-1) and five factor H-related proteins (CFHR-1 to -5) . Members of the H-related protein family are exclusively composed of individually folded protein domains; termed short consensus repeats (SCRs) or complement control modules. FHR1 is produced by hepatocytes and circulates as two differentially glycosylated isoforms (37 kDa and 43 kDa) . Mature human FHR1 is 312 amino acids in length. It contains five; approximately 60 aa SCRs that basically constitute the entire molecule. FHR1 may play a role in complement regulation; lipid metabolism and lipoprotein complexes that bind PMNs to LPS.

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
