Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate RELB in samples. An antibody specific for RELB has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyRELB present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for RELB is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of RELB bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:Bours et al. (1994) demonstrated that human RELB, when generated in mammalian cells, formed kappa-B-binding heterodimeric complexes with p50 (NFKB1) or p52 (NFKB2). Homodimeric complexes of RELB did not show DNA-binding activity.NF-kappa-B-inducing kinase (NIK, or MAP3K14) is required for osteoclastogenesis in response to pathologic stimuli. Vaira et al. (2008) found that overexpression of Relb, but not Rela, rescued differentiation of mouse Nik -/- osteoclast precursors, indicating that blockade of the alternative NF-kappa-B pathway, rather than the classical NF-kappa-B pathway, is responsible for the osteoclastogenic defect in the absence of Nik. Using Relb -/- mice, they showed that Relb itself was required for Rankl-induced osteoclastogenesis in vitro and for TNF-induced bone resorption in vivo
