Serum rheumatoid factor and other IgM class antibodies in IgM anti-CMV(+) versus anti-CMV(-) patients. IgM anti-cytomegalovirus (CMV) (microparticle enzyme immunoassay), rheumatoid factor (RF) (laser nephelometry), IgM or IgG antibodies to mouse IgG, IgM anti-U1snRNP-70 kDa protein (anti-U1–70 k) and anti-β2-glycoprotein I (anti-β2GPI) (ELISA) were performed as described in Materials and methods. Serum dilution for ELISA was 1:100 for IgM class and 1:500 for IgG anti-mouse IgG.
