Biological Activity

Description

Complement factor H/CFH Protein, Human (HEK293, His) is a recombinant complement factor H (CFH) protein with His tag. Human complement factor H, a central complement control protein, is a member of the regulators of complement activation family[1].

Background

Complement factor H (CFH) is a component of the mammalian complement system, which regulates the alternative pathway of complement activation and protects the host cell from inappropriate complement activation. CFH is a key regulator of innate immunity, and CFH deficiency leads to membranoproliferative glomerulonephritis type II[2].

Verified Bioactivity

Immobilized Human CFH at 2 μg/mL (100 μL/well) can bind Anti-CFH Antibody. The ED50 for this effect is 0.2728 μg/mL.
