Nucleotide-containing sorbent for affinity chromatography

Abstract

The invention relates to sorbents for for ›sic! affinity chromatography which are based on hydroxyl-containing base supports on whose surfaces polymers are covalently bonded, characterized in that a) the base support contains aliphatic hydroxyl groups, b) the covalently bonded polymers are bound to the base support by a terminal monomer unit, c) the polymers contain monomer units of the formula II d) the monomer units are linked linearly, ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 independently of one another are H or CH.sub.3, R.sup.4 is H, C.sub.1 -C.sub.5 -alkyl or C.sub.6 -C.sub.12 -aryl, n is an integer between 1 and 5 and one of the radicals X is OH and the other radical X is a nucleoside-containing radical, and to their preparation and use, especially for affinity chromatography.
