ProtoKinetix Commences Organ Preservation Trials


VANCOUVER, British Columbia, Aug. 23, 2005 (PRIMEZONE) -- Following PKTX's (OTCBB:PKTX) successful testing of AFGP on heart cells announced July 18, 2005, the Company has just completed their initial organ preservation trials using heart tissues. The tissue that was treated with AFGP survived in contrast to the untreated tissue that suffered 100% mortality. These tests were conducted over a period of 8 hours at a temperature of 4 degrees C. An independent pathologist validated and corroborated these results.

This dramatically enhanced survivability of heart tissue treated with synthetic AFGP is a vital step toward the development of an effective media for the preservation of organs for transplantation.
