Phosphate ion exchange resin used in the liquid preservation of baboon red cells.

Baboon whole blood, collected in 14 percent citrate-phosphate-dextrose anticoagulant solution in plastic bags was stored in 100-ml aliquots at 4 degrees C for 28 days in the presence or absence of 0.75 grams of phosphate anion exchange resin. In vitro and in vivo measurements after autologous transfusions were made to determine whether the phosphate anion exchange resin had any beneficial effect on the blood during storage.
