Description
Intended Uses: This sandwich kit is for the accurate quantitative detection of human anti-gastric parietal cell antibody (also known as AGPA/PCA) 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 human AGPA/PCA antibody. AGPA/PCA present in the sample is added and binds to antibodies coated on the wells. And then biotinylated human AGPA/PCA Antibody is added and binds to AGPA/PCA in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated AGPA/PCA 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 AGPA/PCA. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm
