[The action of extracellular calcium and the temperature of the isolation of lymphocytes on their viability].

The effect of extracellular calcium binding and temperature of isolation and storage of thymus lymphocytes on their viability was studied. The last was evaluated by the fluorescence intensity of fluoresceindiacetate stained cells and by the intracellular ATP content. The rise of temperature of isolation and storage of lymphocytes from 1 degree to 22 degrees C significantly lowered the intracellular ATP concentration in cells storing in dense suspension [(3-4) x 10(9) lymphocytes/ml].
