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