In the work it has been established, that the exocellular cryoprotectant PEO-1500 inhibits the activity of Ca2+-ATPase of erythrocytes. Kinetic analysis showed that the inhibition of enzyme activity was related to the Vmax alteration, but not to Km for catalytic center with a low affinity of Ca2+-AT...
