title: Sulfhydrylcellulose: a new medium for chromatography of mercurated polynucleotides.
abstract: We have synthesized a new medium, sulfhydrylcellulose, for affinity chromatography of mercurated polynucleotides. It is the product of reaction between aminoethylcellulose and N-acetylhomocysteine thiolactone. Sulfhydrylcellulose carries up to 90 mumol of SH groups/g and is inexpensive, easy to prepare, and stable. Because it binds mercurated RNA specifically and reversibly and exhibits no size discrimination, sulfhydrylcellulose should have wide applications.
