Description

The number of sulfhydryl groups on the surface of intact erythrocytes from patients with polycythemia vera is significantly less (34%) than those from control subjects. Sulfhydryl groups were measured indirectly by reversibly blocking-SH groups with the thiol reagent, 6,6′-dithiodinicotinic acid, which forms stable mixed disulfides on the surface of erythrocytes. Glutathione was used to break the disulfides and release thione into the supernatant. Thione was then quantitated spectrophotometrically.
