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