Abstract
The invention relates to selectively acting polymeric sorbents or saccharides, glycoproteins and saccharide containing polymers. In accordance with the invention, lectins are covalently bonded on vehicles selected from among, oxidized glycosylated hydroxyalkylacrylates or hydroxyalkylmethacrylates, and polyvinyl alcohol. These vehicles are comparable to known materials based on polysaccharides with bonded-on lectins, especially as far as the absorption power of the sorbent is concerned. The preferred process for preparing such sorbents is substantially easier than the hitherto used ones since it does not require specific measures to be taken in the work with highly toxic activating agents, and enables a simple control of conversion degree of the bonding reaction while achieving a relatively high reproducibility. Apart from this, unoxidized saccharide molecules bonded on the vehicle make it hydrophilic, or at least raise its original hydrophility.
