Human IgM ELISA Kit
This Human Immunoglobulin M (IgM) antigen assay is intended for the quantitative determination of total human IgM antigen in serum, plasma, hybridoma cell supernatants, ascites or other biological fluids.
IgM is the first immunoglobulin produced in the immune response and is the third most abundant immunoglobulin in serum. IgM is a disulfide-linked 970kDa pentamer that activates complement and is responsible for red blood cell agglutination. Each monomer consists of two mu heavy chains and two kappa or lambda light chains.
Human IgM will bind to the affinity purified capture antibody coated on the microtiter plate. After appropriate washing steps, horseradish peroxidase labeled polyclonal anti-human IgM antibody binds to the captured protein. Excess antibody is washed away and TMB substrate is used for color development at 450nm. A standard calibration curve is prepared along with the samples to be measured using dilutions of human IgM. Color development is directly proportional to the concentration of total IgM in the samples.
