[Sorption immobilization of glycerol on disperse silica and its interaction with the surface of bovine reproductive cells, seminal plasma and sperm]. / Sorptsionnaia immobilizatsiia glitserina na dispersnom kremnezeme i ego vzaimodeistvie s poverkhnost'iu reproduktivnykh kletok, semennoi plazmoi i spermoi byka.

The binding of hydroxylated disperse silica (I) surface and surface, modified by glycerol (II), with components of above-membrane matrix of bovine reproductive cell and seminal plasma was investigated. It was found that structure of inorganic support defined the character of binding SiO2 with proteins and glycoproteins, including those with hexose and N-acetylneuraminic acid as terminal residue. Value of binding depends on concentration of disperse silica contacting with biomaterial.
