Elevated glutathione accelerates oxidative damage to erythrocytes produced by aromatic disulfide.

Blood 73(1) , 312-7, (1989)

It has been shown that certain dogs have erythrocytes characterized by an inherited high concentration of reduced glutathione (GSH), five to seven times the normal level (high-GSH RBCs). We examined w...

Kinetics of polymerization of hemoglobin S modified by thiol reagents and by oxidation.

Biochim. Biophys. Acta 830(1) , 71-9, (1985)

The effects of four thiol reagents on the kinetics of polymerization of hemoglobin S have been studied in high phosphate buffer (1.8 M), in the presence (3 mM) or absence of sodium dithionite, dependi...
