Complement Factor H (H Factor 1, CFH, HF, HF1, HF2, beta1 H-globulin)

The complement system is a crucial component of the innate immunity against microbial infection. Complement factor H, a 155kD plasma glycoprotein, is an essential regulatory protein that plays a critical role in the homeostasis of the complement system in plasma and in the protection of bystander host cells and tissues from damage by complement activation. Factor H binds to C3b, accelerates the decay of the alternative pathway C3-convertase and acts as a cofactor for the factor Imediated proteolyticinactivation of C3b. In addition, factor H has multiple physiological activities 1) acts as an extracellularmatrix component, 2) binds to cellular receptors of the integrintype, and 3) interacts with a wide selection of ligands, such as the C-reactive protein, thrombospondin, bone sialoprotein, osteopontin, and heparin. Complement factor H has revealed an association with two different renal diseases, glomerulonephritisand atypical hemolytic uremicsyndrome (aHUS).\n\nApplications: \nSuitable for use in ELISA and Western Blot.
