Generic Name: Human Diphtheria Toxin IgM (DT-IgM)ELISA Kit

Purpose

Our Human Diphtheria Toxin IgM (DT-IgM)ELISA Kit is to for the qualitative determination of DT-IgM in Human serum, plasma, culture media or any biological fluid.

Principle

The ELISA is based on the the qualitative enzyme immunoassay technique. The Microplate provided in this kit has been pre-coated with an antigen specific to DT-IgM, make it to solid-phase antigen. Samples are added to the Microplate wells and combined to the specific antigen. Then a Horseradish Peroxidase (HRP)-conjugated antigen specific for DT is added to each Microplate well and incubated, so the antigen-antibody-Enzyme labeled antigen complex is formed. Following a wash to remove any unbound reagent, then the TMB substrate solution is added to each well. Only those wells that contain DT-IgM and HRP conjugated DT antigen will appear blue in color and then turn yellow after the addition of the stop solution. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The qualitative determination of DT-IgM is determined by comparing with the CUTOFF value.
