Description
Intended Uses: This sandwich kit is for the accurate quantitative detection of human Tyrosine Protein Phosphate Non-receptor Type 22 (also known as PTPN22) 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 PTPN22 antibody. PTPN22 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated human PTPN22 Antibody is added and binds to PTPN22 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated PTPN22 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 PTPN22. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm
