Abstract
A method for treating biological tissue is provided in which a cross-linked biological tissue containing free aldehyde groups is reacted with a suitable neutralization agent in order to chemically block the aldehyde groups from reactivity toward cellular proteins. Also provided is the cross-linked biological tissue so produced which is substantially free of reactive aldehyde groups and, as a result, exhibits reduced toxicity and improved biocompatibility.
