H. Pylori IgM
Microplates are coated with H.pylori immunodominant antigens derived from tissue culture of a virulent strain. In the 1st incubation, the solid phase is treated with diluted samples and anti-HP IgM are captured, if present, by the antigens. After washing out all the other components of the sample, in the 2nd incubation bound anti-HP IgM are detected by the addition of anti hIgM antibody, labeled with peroxidase (HRP). The enzyme captured on the solid phase, acting on the substrate/chromogen mixture, generates an optical signal that is proportional to the amount of anti-HP IgM antibodies present in the sample. The presence of IgM in the sample may therefore be determined by means of a cut-off value able to discriminate between negative and positive samples. Neutralization of IgG anti-HP, carried out directly in the well, is performed in the assay in order to block interferences due to this class of antibodies in the determination of IgM.
