The monoclonal antibody 1C11 recognizes Complement Factor I (CFI). CFI is a protein of the complement system (serine protease) , also known as as C3b/C4f inactivator, and is a protein that is encoded by the CFI gene located on chromosome 4. It regulates complement activation by cleaving cellbound or fluid phase C3b and C4b. CFI is synthesised predominantly in the liver, and is initially secreted as a single 88 kDa gene product; this precursor protein is then cleaved by furin to yield the mature CFI protein, which is a disulfide-linked dimer of heavy chain residues (residue 19-335, 51 kDa) and light chain (residues 340-583, 37 kDa). Only the mature protein is active. Genetic polymorphism in CFI has been observed (variants R201S, R406H, R502L). CFI deficiency leads to low levels of complement component 3 (C3) in plasma, due to unregulated activation of the complement alternative pathway, and it has been associated with recurrent bacterial infections in children; more recently, mutations in the CFI gene have been shown to be implicated in development of Haemolytic Uremic Syndrome, a renal disease also caused by unregulated complement activation. The monoclonal antibody can be used to detect CFI levels in serum and plasma.

Application
Immuno assays, Western blot

Application Notes
WB: FI is a 88 kDa heterodimer cleaved out to yield the heavy (50 kDa) and the light (38 kDa) chains (Ref3) IA: The antibody is suitable as both a coat and tracer in immuno assays.

Use
For Western blotting, dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50.

  • NEW Human C3d ELISA
    We are happy to introduce our new ELISA (cat.# HK3017) designed to detect human C3d. What sets this assay apart is its utilization of a distinctive neo-epitope capture antibody that selectively targets a specific C3d region of the alpha chain, which is not available in other C3 variants. This way it specifically distinguishes C3d from native C3… Read more: NEW Human C3d ELISA
