Received December 2, 1977. An easy and efficient procedure for the immobilization of polynucleotide liganda to bisoxirane activated insoluble polysaccharides has been elaborated and is described in this paper. The resulting materials have been applied to the chromatography of DNA polymarase I, and RNA polymerase from E.coli. Because of their extraordinary stability to temperature, formamide, and alka-line conditions they seem to be particularly useful adsorbents for nucleic acid hybridization.
