Abstract
The present invention is a biodegradable, reversibly-swellable, polyvalent cation-binding, protein-based hydrogel which comprises an acyl-modified protein matrix in which the acyl-modified protein matrix is crosslinked with a bifunctional crosslinking reagent, and a method of making the same.
Claims8
A protein hydrogel comprising a protein wherein lysyl residues within the protein are modified by addition of one or more carboxyl moieties thereto to yield an acylated protein by treating the protein with an acylating agent wherein said acylating agent is a tetracarboxylic acid dianhydride, and further wherein the acylated protein is crosslinked with a bifunctional crosslinking reagent wherein the crosslinking reagent is a dialdehyde.
A protein hydrogel comprising:
- a soy protein isolate, said soy protein isolate being acylated by treatment with ethylenediaminetetraacetic acid dianhydride to yield an acylated protein
- said acylated protein being crosslinked with glutaraldehyde.
