This rat FasL BioAssay ELISA Kit is based on the standard sandwich enzyme-linked immunosorbent assay technology. Sample Type:Serum and plasma (heparin, EDTA, citrate), cell culture supernatantsIntended Use:For use in quantitative protein detection, establishing normal range, etc.Sensitivity:<10pg/mlRange:31.2-2000pg/mlSpecificity:Recognizes natural and recombinant rat FasL. This ELISA kit shows no cross-reactivity with other relevant proteins.Test Principle:This assay employs a monoclonal antibody form mouse specific for FasL coated on a 96-well plate. Standards (NSO) and test samples are added to the wells and FasL present in a sample is bound to the wells by the immobilized antibody. A biotinylated detection polyclonal antibody from goat specific for FasL is added subsequently. After washing away the unbound biotinylated antibody with PBS or TBS buffer, Avidin-Biotin-Peroxidase Complex is added to the wells. The wells are again washed with PBS or TBS buffer to remove the unbound conjugates. HRP substrate TMB is used to visualize the HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow color is proportional to the rat FasL captured onto the plate.Kit Components:FasL Microplate coated with anti-rat Ab against FasL, 1x96 wells Lyophilized recombinant rat FasL standard (10ng/vial), 2x vials Biotinylated anti-rat FasL antibody, 1x130ul Avidin-Biotin-Peroxidase Complex (ABC), 1x130ul Sample diluent buffer, 1x30ml Antibody diluent buffer, 1x12ml ABC diluent buffer, 1x12ml TMB color developing agent (Colorless), 1x10ml TMB stop solution, 1x10ml Storage and Stability:Store powder at 4°C liquid at -20°C.
