Ii. Gerashchenko et al., STUDY OF THE REVERSIBILITY OF PROTEIN ADSORPTION ON A DISPERSED SILICA SURFACE, Colloid journal of the Russian Academy of Sciences, 54(4), 1992, pp. 636-639
The interaction of a number of globular proteins with the surface of h
ighly dispersed silica at PH close to the region of the isoelectric st
ate of these proteins was studied by constructing and analyzing adsorp
tion-desorption curves. Complete or partial irreversibility of the ads
orption processes studied was established. It is suggested that the hi
gh sorbability of certain protein preparations may be a consequence of
an increased content of lipids incorporated into the protein structur
e.
