Abstract: 

The effect of placenta extracts fractions on the thermal denaturation of erythrocyte membrane-bound proteins is investigated by differential adiabatic scanning calorimetry. Four transitions are registrated on a denaturation thermogram of white erythrocyte ghosts. Adding the placenta extracts fractions to the suspension of erythrocyte membrane-bound proteins leads to increasing the temperature of all protein groups except spectrin.

Keywords: differential scanning calorimetry, erythrocyte ghosts, placenta extracts fractions, thermal denaturation
