The influence of age on the thermal transition of serum albumine in rats.
Serum albumine from rats at different ages (1, 3, 9, 18 months) undergoes a thermal reversible denaturation in the range of 40-53 degrees C. Thermal transitions of unbuffered solution of native protein show a significant change of pH as they became heat denaturated. The protein molecule has been analysed in melting studies, manifested by cooperative dissociation of protons and it experiences a decrease in temperature transition with the younger the rats.
