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