520 3 |a Raman spectroscopy was used to investigate changes in hemoglobin conformation and its ability to transfer O2 and NO induced by activation of purinergic receptors of erythrocytes with extracellular ATP. It was found that addition of ATP in a final concentration of 0.1 mM and higher to erythrocyte suspension was followed by changes in hematoporphyrin conformation, while addition of ATP in a concentration of 1 mM and higher increased the proportion of oxyhemoglobin and NO-associated hemoglobin complexes. In case of purinergic receptors activation in blood erythrocytes, significant changes in hemoglobin conformation were observed only at a final ATP concentration of 5 mM, probably due to buffer properties of the blood.
