Storage Instruction
If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual.
This kit recognizes Human CFH in samples. No significant cross-reactivity or interference between Human CFH and analogues was observed.

Additional Info
Post Translational Modifications
Sulfated on tyrosine residues. According to a report, Asn-217 is not glycosylated. Another study observed glycosylation at this position.
Function
Glycoprotein that plays an essential role in maintaining a well-balanced immune response by modulating complement activation. Acts as a soluble inhibitor of complement, where its binding to self markers such as glycan structures prevents complement activation and amplification on cell surfaces. Accelerates the decay of the complement alternative pathway (AP) C3 convertase C3bBb, thus preventing local formation of more C3b, the central player of the complement amplification loop. As a cofactor of the serine protease factor I, CFH also regulates proteolytic degradation of already-deposited C3b. In addition, mediates several cellular responses through interaction with specific receptors. For example, interacts with CR3/ITGAM receptor and thereby mediates the adhesion of human neutrophils to different pathogens. In turn, these pathogens are phagocytosed and destroyed. (Microbial infection) In the mosquito midgut, binds to the surface of parasite P.falciparum gametocytes and protects the parasite from alternative complement pathway-mediated elimination.
