Abstract: The invention relates to a method of cross-linking poly(amino acid) compounds (e.g. proteins, polypeptides, protein polymers, etc.) to each other or attaching such compounds to polyamino or polycarboxyl compounds. The method involves lyophilizing a solution of at least one poly(amino acid) compound, or at least one poly(amino acid) compound and a polyamino or polycarboxyl compound, maintaining the lyophilized solid under vacuum, heating the lyophilized solid under vacuum to an elevated temperature effective to cause cross-linking without denaturing of the poly(amino acid) compounds, and cooling the product and releasing the vacuum. The method produces cross-linking without the use of activating compounds or cross-linking molecules. The invention also relates to novel cross-linked products.

Abstract: The present invention relates to polymerizable monomers for applications in medicine and biotechnology and synthesis thereof. The polymerizable ligands containing NAcetyl Glucosamine bind more strongly to lysozyme than NAG itself. The binding is further enhanced when a spacer arm, for example 6-Amino Caproic Acid (6-ACA) is introduced in the structure. The conjugated ligands could be used for prevention and treatment of bacterial and viral infections Moreover these ligands can be coupled to stimuli sensitive polymers and used for the recovery of biomolecules The methodology can be extended to other ligands such as sialic acid and the corresponding polymers used for preventil1g influenza and lor rotavirus infections
