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