title: [Development and experience in the use of an immunoenzyme test system for determining specific antihemolysins in patients with measles].
abstract: To determine the physico-chemical nature of specific antimeasles antihemolysins, an enzyme immunoassay (EIA) system with the use of stable measles virus hemolysing antigen has been developed. The expedient method has been worked out: the antigen diluted 1:20 with the initial hemolytic activity in the direct hemolysis inhibition test equal to 1:64 and, for its fixation, 0.1 M carbonate-bicarbonate buffer solution, pH 9.6, are used; the fixation of the antigen is carried out at 4 degrees C for 16-20 hours. The final dilution of the serum, whose coloration significantly differs from that of the control, is considered to be the titer of antimeasles antihemolysins. Specific antihemolysins belonging to three classes of immunoglobulins, A, M and G, are synthesized in measles. The detection of IgM-antihemolysins in high titers on the first day of rash opens prospects for using the newly developed EIA system for the rapid diagnosis of measles.
