The Human B cell Activating Factor belonging to the TNF Family (Hu BAFF) ELISA quantitates Hu BAFF in human serum, plasma, cell culture supernatants or other body fluids. The assay will exclusively recognize both natural and recombinant Hu BAFF.
Principle of the method
The Human BAFF solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the binding of the second (detector) antibody to the target on a different epitope from the capture antibody. An antibody conjugated with enzyme binds the formed sandwich. After incubation and washing steps to rid the microplate of unbound substances, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Rigorous validation
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.
BAFF is a membrane bound cytokine expressed by B cell lineage cells. The soluble form of the cytokine binds to the receptors TNFRSF13B/TACI, TNFRSF17/BCMA, and TNFRSF13C/BAFFR. BAFF is a potent B cell activator, and important for the proliferation and differentiation of B cells. BAFF is also expressed by T lymphocytes and has been shown to promote T cell activation and survival. Isoforms representing alternatively spliced, and glycosylated variants have been identified.
