Method Description
The SeraQuest mumps IgM assay is an enzyme capture method. Diluted samples are incubated in wells coated with antihuman-IgM monoclonal antibodies. If present, IgM antibodies are captured in the wells. Wells are washed, removing excess sample. Conjugate-antigen complex (mumps antigen in a complex with monoclonal antibodies conjugated to horseradish peroxidase) is added, and the wells are incubated. IgM antibodies specific for the antigen will bind the conjugate. Wells are washed, removing excess conjugate. Peroxidase substrate is added, and the wells are incubated. Stop solution is added converting the substrate to a yellow end product, which is read photometrically.(Package insert: Mumps IgM. Quest International; V 04/2018)
