VANCOUVER, Feb 19, 2009 (BUSINESS WIRE) --
PKTX | Quote | Chart | News | PowerRating -- Protokinetix' (PKTX) results over the last 2-years have clearly shown
the vital role that AAGP(TM) can play in this exciting disease treatment
arena. Support for stem cell research has never been stronger and
continues to grow. This growth will accelerate as successful results are
announced.

One of the most important ingredients for the success of this therapy is
the recovery of the maximum number of viable stem cells after storage.
These extremely delicate cells typically have a very low yield after
cryopreservation. AAGP(TM) testing that has been conducted on stem cell
preservation at all temperatures has shown an impressive increase in
survivability and viability.

In summary, over the past 24-months, AAGP(TM) has demonstrated a remarkable
increase in viable cell recovery at temperatures ranging from -196EsC
(cryopreservation) all the way to 37EsC (body temperature). These results
have been consistent regardless of the source of the stem cells. As an
example, AAGP(TM) has been independently tested as a protective agent in
the cryopreservation (-196EsC) and subsequent thawing of umbilical cord
blood in low concentrations of AAGP(TM) (4mg/ml). The resultant analysis
revealed a more than double average increase over the control group
(cells not protected with AAGP(TM)) in the yield, following thawing.
