Erythrocyte insulin receptors remain intact through three days of storage

The status of the erythrocyte insulin receptor was investigated prior to and during storage at 4C in acid-citrate dextrose (ACD) solution. The receptors on cells that were obtained from both resting and exercised fasting subjects and stored for up to three days in ACD were unchanged as evaluated by both maximal specific hormone binding and the concentration of insulin required to one half maximally inhibit specific binding. These findings …
