Preliminary assessment of nuclear DNA content in Chondrilla (Asteraceae) plants of European Russia and Western Kazakhstan using fl ow cytometry

 Preliminary data on the genome size of representatives of the genus Chondrilla (Asteraceae) of European Russia and Western Kazakhstan were obtained using fl ow cytometry. Among all studied specimens of the genus, for specimens of C. ambigua and C. pauciflora, a direct dependence of the genome size on the number of chromosomes was established. In our study, the DNA content of the diploid C. ambigua was 2С = 1.69 pg, and that of the triploid C. pauciflora was 2С = 2.65 pg.

Flow Cytometry Investigations Indicators Light Scattering in the Heterogeneous Population Immune System Cells from Mice Immunized with F1 Capsular Antigen, Yersinia pestis

Aim – heterogeneous populations of blood leukocytes and abdomi- nal cavity of mice immunized with a capsular antigen of a plague microbe. Male mice of the BALB / c line were used in the work. The reaction of the cells of the immunophagocytic system was assessed by flow cytometry, in terms of the intensity of direct and lateral light scattering, correlating with changes in the cell volume and intracellular granularity.
