Crosslinked tissue is contacted with one or more toxicity reducing solutions to remove cytotoxicity associated with the crosslinking process. In particular, crosslinked tissue can be contacted with an inorganic sulfur-oxygen group to form chemical adducts of aldehydes and the inorganic sulfur-oxygen group. Preferably, the cytotoxicity reduced crosslinked tissue has no residual cytotoxicity. In preferred embodiments, a plurality of toxicity reducing agents are used to detoxify the tissue. Preferred toxicity reducing agents include, for example, inorganic sulfur-oxygen ions, such as bisulfate and thiosulfate, organic sulfates, amines, ammonia/ammonium, and surfactants. |
