  • Hematology control or calibrator with red cell components of enhanced stability
    Patent number: 4777139
    Abstract: Red cells are exposed to an unsaturated aldehyde such as acrolein (propenal) under conditions sufficient to increase the stability of the cells without impairing the ability of a lysing reagent to lyse the cells. After treatment, the treated cells are washed and are suspended in a stabilizing suspension medium.

  • Stabilizing blood cells with aromatic polyaldehyde for use in hematology controls and calibrators
    Patent number: 4698312
    Abstract: Blood cells such as erythrocytes of animal origin are treated with a solution containing water, an organic cosolvent (such as dimethylsulfoxide, alone or admixed with a polyol), an aromatic polyaldehyde (such as phthaldialdehyde) and optionally salts and buffers. In an illustrative case, the treating solution is hypertonic and shrinks goat erythrocytes to the size of human platelets.
