The rat ICAM1 (Intracellular adhesion molecule 1 or CD54) BioAssay ELISA Kit is based on the standard sandwich enzyme-linked immunosorbent assay technology. Sample Type:Serum and plasma (heparin, EDTA), cell culture supernatants. Intended Use:For use in quantitative protein detection, establishing normal range etc. Sensitivity:<2pg/mlRange:31.2-2000pg/mlSpecificity:Recognizes natural and recombinant rat ICAM-1. This ELISA kit shows no cross-reactivity with other relevant proteins.Test Principle:This assay employs a monoclonal antibody from mouse specific for ICAM-1 coated on a 96-well plate. Standards (NSO) and test samples are added to the wells and ICAM-1 present in a sample is bound to the wells by the immobilized antibody. A biotinylated detection polyclonal antibody from goat specific for ICAM-1 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 ICAM-1 captured onto the plate.
