Michael -- is this frozen *whole* blood? Or when you donate
blood do they immediately separate out the white blood cells?
[Presumably they would cause (or themselves produce) an immune
system reaction in whomever receives the blood]. If so all
you have in stored blood is red blood cells, platelets, the
other clotting factors and soluble plasma proteins.
Comments Rafal?
[Is the problem that they are just freezing the blood at -10 C?
Do you get a longer lifetime if they freeze it in LN2?]
Now of course what is interesting from our extropic life-extension
perspective is that we *want* that fraction of the blood with the WBC
because that is most likely the fraction that contains the circulating
stem cells -- when you see a company that is offering to identify those
cells, separate them and store them frozen in LN2 at the bottom of the
Homestake mine -- *buy* stock in it my friends.
