FIELD: biotechnology.
SUBSTANCE: cells are isolated from human or animal biological tissues, labeling is carried out using a fluorescent dye, co-culturing is carried out with the diseased cells, the test substance is added to co-culture, the biological activity of the test substance is determined analysing the viability of a certain cell population in the co-culture of healthy and diseased cells according to increase or reduce the percentage of dead cells.
EFFECT: increasing the reliability of the result of determining the biological activity of substances and enlarging the area of application of methods of determining the biological activity of substances.
