Patent ID: 8735054

Claim:
A composition comprising: an acellular tissue matrix; and a solution, wherein the solution comprises: a biocompatible buffer; a salt at a concentration of up to about 150 mM in the solution; a surfactant in an amount of about 0.2% (w/v) or less of the solution; a transition-metal chelator at a concentration of ranging from about 1 mM to about 10 mM; a tissue stabilizer in an amount of up to about 10% (w/v) of the solution; and a biocompatible co-solute in an amount of up to about 20% (w/v) of the solution, wherein the solution has a pH ranging from about 5.2 to about 6.9 and wherein the solution and tissue matrix are selected to provide a water activity ranging from about 0.930 to 0.995 when the tissue matrix is contacted with the solution.
