Enzyme ImmunoAssay (ELISA) for the semi-quantitative determination of IgG antibodies to Measles Virus in human plasma and sera. The product is intended mostly for the follow-up of anti Measles Virus vaccination and can also be useful for the follow up of infected individuals.
Micro-plates are coated with Measles Virus native antigens derived from tissue culture of a virulent strain. In the 1st incubation, the solid phase is treated with diluted samples and anti Measles Virus IgG are captured, if present, by the antigens.After washing out all the other components of the sample, in the 2nd incubation bound anti Measles Virus IgG are detected by the addition of anti hIgG 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 Measles Virus IgG antibodies present in the sample. IgG in the sample may therefore be semi quantitated in arbU/ml by means of its S/Co value and a calibration curve.
