B-1,3-GLUCAN-DERIVED POLYALDEHYDE/POLYAMINE HYDROGEL

摘要

The present invention provides a combination product which comprises: (1) a polyaldehyde obtained by introducing an aldehyde group into a branched glucose in a &bgr;-1,3-glucan, and (2) a polyamine obtained by increasing the molecular weight of a poly-L-lysine. The combination product according to the present invention is useful as a material for a tissue adhesive hydrogel which can be used as a hemostatic agent or the like which exhibits low risks for viral infections and the like, high biodegradability and biocompatibility, excellent safety, a good adhesion rate and a good adhesion strength.
