[Polymer-modified silica sorbents for molecular sieve chromatography of biopolymers]

N-vinylpyrrolidone-N(2-hydroxy) acrylamide copolymer-modified porous glass was studied as a support for gel permeation chromatography. Influenza, Sendai, fowl plague viruses and rota-viruses were purified by chromatography on the support. As compared with Sepharose 4B the support shows better hydrodynamic properties and yields higher amounts of purified viruses. The support can be also applied to the t-RNA and ribosomes separation.
