Abstract
A process for preparing a porous solid material for use in a chromatography column and which is capable of fixing reversibly biological macromolecules comprises coating a porous inorganic support with a polysaccharide polymer having .alpha.-glycol groups which undergo oxidative scission, subjecting the polysaccharide polymer to an oxidative scission reaction, reacting the resulting oxidized polysaccharide polymer with an amino molecule or macromolecule having the formula R'--NH.sub.2 to produce a polysacchride polymer having the formula R.sub.4 --CH.dbd.N--R' and reducing the imine bond in said immediately above defined polysaccharide polymer to a stable amine bond.
