    URANO Hiromi , FUKUZAKI Satoshi

    … The intrinsic viscosity of BSA increased with increasing ionic strength in all the buffer solutions. … From these results, the repression of BSA adsorption onto oxides was ascribed to the masking of adsorbing sites on the oxide surfaces and partial desorption of adsorbed BSA induced by adsorption of anions of carboxylic acids and phosphate, as well as to the expansion of the BSA molecule due to the charge-shielding action of buffer salt ions. …
