A magnetic microsphere assay utilizing a novel recombinant Rubella antigen for the detection of Rubella IgM antibodies

In this application note, Merck presents semi-automated processes, both for coupling Rubella antigen on magnetic microspheres and for performing a Rubella IgM assay workflow. Detection of Rubella IgM antibodies from human serum samples is carried out by fluorescent readout in a flow cytometer.
