Complement factor B (CFB), a key enzyme in innate immunity’s complement system, safeguards against microbial threats and has emerged as a crucial biomarker in clinical settings. Vital for the alternative complement pathway’s activation, CFB’s regulation is critical, particularly for protecting against encapsulated bacterial infections. Clinically, its deficiency links to increased susceptibility to infections such as; pneumococcal and meningococcal infections. Moreover, CFB’s diagnostic potential in pancreatic cancer is noteworthy; when combined with CA19-9 in the ComB-CAN panel, it significantly enhances early detection accuracy. Additionally, CFB may contribute to tumor growth by activating the PI3K-AKT pathway, making it an important focus for cancer screening and research.

Application

The Human Factor B ELISA kit is to be used for the in vitro quantitative determination of Factor B in plasma and serum samples. This kit is intended for laboratory research use only and is not for use in diagnostic or therapeutic procedures.

Principle

The Human Factor B ELISA is a ready-to-use solid-phase enzyme-linked immunosorbent assay based on the sandwich principle with a working time of 3½ hours. The efficient format of a plate with twelve disposable 8-well strips allows free choice of batch size for the assay. Samples and standards are incubated in microtiter wells coated with antibodies recognizing Human Factor B. Biotinylated tracer antibody will bind to the captured Human Factor B. Streptavidin-peroxidase conjugate will bind to the biotinylated tracer antibody. Streptavidin-peroxidase conjugate will react with the substrate, tetramethylbenzidine (TMB). The enzyme reaction is stopped by the addition of oxalic acid. The absorbance at 450 nm is measured with a spectrophotometer. A standard curve is obtained by plotting the absorbance (linear) versus the corresponding concentrations of the Human Factor B standards (log).  The Human Factor B concentration of samples, which are run concurrently with the standards, can be determined from the standard curve.

Linearity

Linearity of 6 EDTA plasma samples was determined. CV of the samples is between 6.0 and 11.4.

Precision and reproducibility

The intra-assay was tested by testing 3 EDTA plasma samples in quadruple and was between 3.4 and 10.7%. The inter-assay was tested by testing 3 EDTA plasma samples in quadruple and was between 2.8 and 9.7%.
