I am using 180 USP U/mg Heparin sodium salt. I have seen that 10-30 units/mL of blood is the accepted range. Would that mean that I would need 55.5ug of heparin salt per mL of blood? IS my math right there?
I am also wondering if I were to spray dry some tubes with this, could I dilute this into PBS or distilled water and let it evaporate overnight? What would be the proper dilution there?
