[A comparison of the sorption capability and standardization of plates of different shapes for immunoenzyme analysis].

The sorption characteristics of ELISA plates manufactured by the Moscow and Leningrad plants and by some foreign firms are compared. Sorption activities and standard specifications of the plates for chemically heterogeneous antigens like ovalbumin or Shigella sonnei lipopolysaccharides and for complex antigens like Mycobacterium tuberculosis or S. sonnei ribosomal fractions have been examined. Sorption activities of the plates varied in tests with different antigens. The sorption activity and the standard specifications of the plates manufactured in Leningrad have been found in fact the same as of the foreign plates with all the antigens examined, whereas the Moscow plates have been inferior to both.
