摘要

A method is described for the preparation and storage of baboon red blood cells, frozen, in the original polyvinylchloride (PVC) plastic collection bag. Up to four hundred fifty (450 + 45 ml) ml of blood is collected in a quadruple plastic bag system with a special adaptor port on the tubing connecting the primary 800 ml PVC plastic bag to the three transfer packs. The red cells are concentrated by centrifugation of the primary collection bag and all of the plasma is expressed into one of the integrally attached transfer packs. The red cell concentrate in the 800 ml primary collection bag with a hematocrit of 75 +/- 5 V% is stored with an empty integrally attached transfer pack. Glycerol solution is added through the collection line of the primary 800 ml collection bag. Three aliquots of glycerol solution are introduced with short equilibration periods between each addition. The red cells are then concentrated by centrifugation, the supernatant glycerol is transferred into the empty integrally attached transfer pack and discarded. The glycerolized packed red cells are then frozen. The procedure uses a high concentration of glycerol (40% w/v) and mechanical refrigeration at -80 C for the freezing and storage of the product.
