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