Property peculiarities of the atelocollagen-hyaluronan conjugates crosslinked with a short chain di-oxirane compound.

Minimal amounts of a short-chain bifunctional crosslinker of about 1.3 nm length, the 1,4-butanediol-diglycidyl ether (BDDGE), were used to generate atelocollagen-hyaluronan conjugates in hydrogel state. Two a priori constraints were considered in recipe/procedure developing: (i) working in nondenaturing conditions, and (ii) ensuring a low cytotoxicity of the final product.
