[Determination of the sorption properties of microplates for immunoenzyme analysis].

The authors have examined the possibility of using horse radish peroxidase for assessment of the sorption characteristics of microplates for enzyme immunoassay; the results obtained by the technique modified by the authors and by one of the routine methods (the direct method) were in high correlation. Sorption capacities and homogeneity of the plates manufactured in Leningrad and abroad were compared; the plates made in this country were found inferior to foreign ones in respect of both parameters almost twofold. Sorption capacity of the microplates may be improved by gamma-irradiation; the optimal irradiation dose was defined: 1.5 mrad.
