Popis: A modification of Krijnen's cryopreservation method, using low intracellular concentrations of 17.5% glycerol and extracellular 4% sorbitol as additives, has been developed for liquid nitrogen freezing of small volumes of erythrocytes for a test cell panel. A technique for their subsequent successful storage in sterile, dextrose-electrolyte maintenance solution (CP-2) at 4°C after recovery is presented. By these procedures, the mean recovery of red cells after lytic losses from freezing and thawing injury was 94.1%. The manipulations involved in transferring, mixing and resuspending the red cells removed an additional 11.1–16.2%, resulting in an overall recovery of 80.5% for serologic tests. Less than 3% of the cells exhibited cumulative lysis at seven days maintenance in CP-2 solution at 4°C, and the blood group antigens examined remained as potent as those in sterile, fresh ACD blood.
