Description
Intended Uses: This sandwich kit is for the accurate quantitative detection of human Neopterin (also known as NEOP) in serum, plasma, cell culture supernates, cell lysates, tissue homogenates.
Principle of the Assay: This kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with human NEOP antibody. NEOP present in the sample is added and binds to antibodies coated on the wells. And then biotinylated human NEOP Antibody is added and binds to NEOP in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated NEOP 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 human NEOP. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm
