Promethean is the leader in processing human skin allograft for use as a sterile medical product. Promethean’s initial product, GammaGraft®, is the first irradiated human skin allograft storable at ambient temperature.  Repriza®, a sterile Acellular Dermal Matrix, is an excellent graft for reinforcing the abdominal wall during hernia surgery or as a bolster for breast reconstruction following mastectomy.

Human skin allograft has long been considered the Gold Standard for wound care.  Most health care professionals, outside of regional burn centers, have not had access to human skin allograft.  At last there is a Human Skin Allograft that is storable at ambient temperature and ready for application upon opening a foil pouch. This allows physicians everywhere to benefit from the use of allograft skin.


Promethean has been processing sterile allografts for over 20 years.  We have an unparalleled history of safety and quality products.  We are proud to have helped heal tens of thousands of wounds and patients.


Promethean’s grafts are some of the most cost-effective on the market.  This is very important in the evolving healthcare environment where 20% co-pays for patients can amount to thousands of dollars and high-deductible health plans mean the patient will pay a substantial portion of their bills. Learn how GammaGraft and Repriza can be a low-cost solution for your needs.
