Effects of anion transport inhibitors on hemolysis of human erythrocytes under hydrostatic pressure.

abstract：:Fibronectin contains at least two distinct oligopeptide sequences serving as signals for the interaction with cell surface adhesion receptors termed integrins. One of these sequences, Arg-Gly-Asp-Ser (RGDS) tetrapeptide, was shown to be transferred to a truncated form of Staphylococcal IgG-binding protein (hereafter r...
