 Specificity    This assay has high sensitivity and excellent specificity for detection of CFB. No significant cross-reactivity or interference between CFB and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between CFB and all the analogues, therefore, cross reaction may still exist in some cases.

 Preparation and Storage    Store all reagents at 2-8 degree C.
 Sample Preparation    We suggest pre-experimenting with neat (undiluted) samples, 1:2 or 1:4 dilutions. Please avoid diluting your samples more than 1:10 as it would exceed the dilution limit set for this kit. If the expected concentration of the target is beyond the detection range of the kit, please contact technical support.
 Other Notes    Small volumes of CFB elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
 Searchable Terms for CFB purchase    MBS721316 is a ready-to-use microwell, strip plate Competitive or Sandwich ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Complement Factor B (CFB) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing CFB, with an estimated sensitivity of 0.1 mug/mL. The ELISA analytical biochemical technique of the MBS721316 kit is based on CFB antibody-CFB antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect CFB antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, CFB. Appropriate sample types may include undiluted human body fluids and/or tissue homogenates, secretions such as Serum, plasma, Cell Culture Supernatants, body fluid and tissue homogenate. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Product Description specifically for CFB elisa kit

   Principle of the assay: CFB ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-CFB antibody and an CFB-HRP conjugate. The assay sample and buffer are incubated together with CFB-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the CFB concentration since CFB from samples and CFB-HRP conjugate compete for the anti-CFB antibody binding site. Since the number of sites is limited, as more sites are occupied by CFB from the sample, fewer sites are left to bind CFB-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The CFB concentration in each sample is interpolated from this standard curve.

 NCBI Summary for CFB    This gene encodes complement factor B, a component of the alternative pathway of complement activation. Factor B circulates in the blood as a single chain polypeptide. Upon activation of the alternative pathway, it is cleaved by complement factor D yielding the noncatalytic chain Ba and the catalytic subunit Bb. The active subunit Bb is a serine protease which associates with C3b to form the alternative pathway C3 convertase. Bb is involved in the proliferation of preactivated B lymphocytes, while Ba inhibits their proliferation. This gene localizes to the major histocompatibility complex (MHC) class III region on chromosome 6. This cluster includes several genes involved in regulation of the immune reaction. Polymorphisms in this gene are associated with a reduced risk of age-related macular degeneration. The polyadenylation site of this gene is 421 bp from the 5' end of the gene for complement component 2. [provided by RefSeq, Jul 2008]
Section Bar
 UniProt Comments for CFB    CFB: Factor B which is part of the alternate pathway of the complement system is cleaved by factor D into 2 fragments: Ba and Bb. Bb, a serine protease, then combines with complement factor 3b to generate the C3 or C5 convertase. It has also been implicated in proliferation and differentiation of preactivated B- lymphocytes, rapid spreading of peripheral blood monocytes, stimulation of lymphocyte blastogenesis and lysis of erythrocytes. Ba inhibits the proliferation of preactivated B-lymphocytes. Defects in CFB are a cause of susceptibility to hemolytic uremic syndrome atypical type 4 (AHUS4). 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. Belongs to the peptidase S1 family. 2 isoforms of the human protein are produced by alternative splicing.
