[Characteristics of isoelectric fractions of human serum albumin].
Amino acidic composition, dispersion of optic rotation, differential temperature-perturbation spectra, molecular weight and terminal amino acids are studied for certain isoelectric fractions of human serum albumin obtained by means of isoelectric focusing in the borate-polyol system. The isolated three isoelectric fractions with pI 4.7, 4.9 and 5.1 revealed no significant differences in the composition of amino acids. They also did not differ in molecular weight and N- and C-terminal amino acids. However certain differences in the conformation and number of perturbed thyrosils are detected by means of spectral methods.
