Q

What is the role of ATP and 2,3-DPG as it pertains ot RBC survival

A
  • ATP helps RBCs move Na+ and Ca2+ out of the cell

- 2,3-DPG controls hemoglobin affinity for O2

Q

Centrifugation process of cryoprecipitate

A

WB → hardspin → plt-poor plasma → freeze plasma → thaw plasma in 1-6°C waterbath → “Cryo” will precipitate in cold → hardspin → remove cryo-poor plasma, leaving cryo precipitate in the bag
