products gene name :
[CFI]
other gene names :
[Cfi; Cfi; If]
purity :
Antigen-specific affinity chromatography followed by Protein A affinity chromatography
form :
Supplied as solution form in PBS, pH7.4, containing 0.02% NaN3, 50% glycerol.
storage stability :
Storage: Avoid repeated freeze/thaw cycles. Store at 4ºC for frequent use. Aliquot and store at -20ºC for 12 months. Stability Test: The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the
expiration date under appropriate storage condition.
tested application :
Western Blot (WB), Immunohistochemistry (IHC), Immunocytochemistry (ICC), Immunoprecipitation (IP).
app notes :
Western blotting: 0.5-2 ug/mL;1:500-2000. Immunohistochemistry: 5-20 ug/mL;1:50-200. Immunocytochemistry: 5-20 ug/mL;1:50-200. Optimal working dilutions must be determined by end user.

ncbi summary :
This gene encodes a serine protease that plays an important role in the classical and alternative complement pathways where it cleaves C4b and C3b components of C3 and C5 convertases. The encoded preproprotein undergoes proteolytic processing to generate an active, disulfide-linked heterodimeric enzyme comprised of heavy and light chains. [provided by RefSeq, Jul 2016]
uniprot summary :
CFI: Responsible for cleaving the alpha-chains of C4b and C3b in the presence of the cofactors C4-binding protein and factor H respectively. Defects in CFI are a cause of susceptibility to hemolytic uremic syndrome atypical type 3 (AHUS3). An atypical form of hemolytic uremic syndrome. It is a complex genetic disease characterized by microangiopathic hemolytic anemia, thrombocytopenia, renal failure and absence of episodes of enterocolitis and diarrhea. In contrast to typical hemolytic uremic syndrome, atypical forms have a poorer prognosis, with higher death rates and frequent progression to end-stage renal disease. Susceptibility to the development of atypical hemolytic uremic syndrome can be conferred by mutations in various components of or regulatory factors in the complement cascade system. Other genes may play a role in modifying the phenotype. Defects in CFI are the cause of complement factor I deficiency (CFI deficiency). CFI deficiency is an autosomal recessive condition associated with a propensity to pyogenic infections. Belongs to the peptidase S1 family.
