Abstract
A biocompatible graft material and a method for making the same are disclosed. The method of making the graft material involves freezing and subsequently thawing a donated tissue sample in a bleach solution. The tissue is then washed in a detergent solution, treated with antimicrobial agents, and soaked in a hypertonic solution. The tissue is thereafter treated with sodium hydroxide and later hydrogen peroxide to yield the desired biocompatible graft material.
