Hello I have some 40 doses of frozen blood plasma from different people, I have to study the optics of wholeblood. Is it possible to just mix it with (lets say 40%) of fresh red blood cells. Will this do any harm the the biochemistry? In that case What if I'll do it by my self? just letting the blood cells fall to the bottom of the vial at seperate it. Will this change ex. proteins in the plasma?
