Fibronectin is a 430kD dimeric glycoprotein that exists in 2 forms - cellular and plasma fibronectin. Sample Type:Serum and plasma (heparin, EDTA, Citrate), cell culture supernatants Intended Use:For quantitative protein detection, establishing normal range.Sensitivity:<15pg/mlRange:156-10,000pg/mlSpecificity:Recognizes native and recombinant rat Fibronectin. This ELISA kit shows no cross-reactivity with other relevant proteins.Test Principle:This rat Fibronectin BioAssay ELISA Kit is based on the standard principle of a sandwich enzyme-linked immunosorbent assay. A mouse monoclonal antibody specific for rat Fibronectin is coated on a 96-well plate. Standards and test samples are added to the wells and Fibronectin present in a sample is bound by the immobilized antibody. A biotinylated polyclonal antibody from goat specific for Fibronectin 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 product that changes into yellow after adding acidic stop solution. The density of yellow color is proportional to the rat Fibronectin captured onto the plate.Kit Components:Microplate coated with anti-rat monoclonal Fibronectin antibody, 1x96 wells Lyophilized native rat Fibronectin standard (10ng/vial), 2x vials Biotinylated anti-rat Fibronectin 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.
