title: [Structural transformation of human erythrocyte membranes initiated by group specific antibodies].
abstract: Some changes have been found in the rates of the desintegration by sodium dodecylsulfate of human erythrocite membranes (EM) after incubation with specific group antibodies (GA) from incompatible blood. GA have no effect on the disintegration rates of EM by sodium desoxycholate and Triton X-100. The data are considered as the evidence of the structural transition in EM induced by GA and resulting in modification of integrative coupling forces primarily in the protein components of the membrane. The stopflow technique has been used to investigate the dependence of the desintegration rates in the quick phase (10 to 100 ms) upon the GA concentrations in the incubation medium and upon the incubation time. The obtained curves are distinctly S-shaped that is peculiar of cooperative processes.
