    Abstract:
    With the help of indirect immunofluorescence on the model systems--a ploid line of wheat, haploid and diploid cells of Chlamydomonas reinhardii, glass beads with adsorbed histones--a study was made of the dependence of ultimate dilutions (UD) of antihistone sera on the quantity, density and immunochemical properties of histones--antigens. The UD value in the artificial model system (glass beads) increased with the rise in the quantity and density of histones on bead to some definite limits, and then the UD remains constant to be determined only by the titre of antiserum. In natural model system (wheat, Chlamydomonas reinhardii), with the rise in quantities of DNA and histones in the nucleus their densities remain constant, with no changes of UD values being observed. The results obtained are discussed in terms of establishing the dependence of UD on immunochemical properties of histones-antigens. Thus, the method of indirect immunofluorescence may be used for comparative analysis of immunochemical properties of histones in various objects.
