Description
Intended Uses: This sandwich kit is for the accurate quantitative detection of Rat Fatty Acid Binding Protein (also known as FABP4) in serum, plasma, cell culture supernates, cell lysates, tissue homogenates.
Principles of the Assay: This kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with Rat FABP4 antibody. FABP4 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Rat FABP4 Antibody is added and binds to FABP4 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated FABP4 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Rat FABP4. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm
