VANCOUVER, British Columbia--(Business Wire)--
ProtoKinetix (OTCBB: PKTX) (www.protokinetix.com), a biotechnology company that
has developed and patented a family of synthetic anti-aging glycopeptides (AAGP)
for medicine and the biotechnology and cosmetic industries today announced, as a
follow up to recent news on the research done by ProtoKinetix` lead scientific
investigator, Dr. Samer Hussein, the Company announces some of his findings as
related to stem cell recovery.
Using a standard cryogenic protocol for stem cell storage, the addition of
2mg/ml of AAGP resulted in an extraordinary recovery of 87-percent. Traditional
recovery rates after cryopreservation with DMSO are typically between 30 and
40-percent.
In addition to the value of AAGP in cryopreservation (frozen to -196?C), a set
of trials designed to determine whether AAGP treated stem cells could survive
after refrigeration (4?C) were conducted. After 3-days of refrigeration,
untreated cells have a very high mortality rate. These trials found that AAGP
can significantly reduce cell death rate. AAGP demonstrated an impressive and
repetitive 8 to 12-times increase in cell viability and survivability.
"Preservation of stem cells is getting to be more and more popular given the
disease fighting regenerative ability of the stem cells. These results with AAGP
opens up an ever expanding market for ProtoKinetix which we fully intend to take
advantage of, said Ross L. Senior, President and CEO of ProtoKinetix, Inc.
