Thiol gels are prepared from hydroxyl containing polymers by forming a 2-fluoro-1-methylpyridoxy derivative of the polymer followed by reacting the derivative with sodium dimethyldithiocarbamate and reducing to produce a sulfhydryl substituted polymer. Alternatively, the derivative is reacted with dithiothreitol to produce a sulfhydryl substituted polymer having free sulfhydryl groups spaced from the polymer. The thiol gel can be activated by means of 2,2'-dipyridyl disulfide and reacted with a free sulfhydryl containing biologically active ligand in order to provide an insolubilized ligand which can be used for various purposes including use as an immobilized biologically active material or use as a matrix in covalent chromatography.
