the molecular weight of high affinity [ 3h ] pyrilamine binding sites on differentiated cells were approximately 68,000 as analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis , which after treatment with n-glycanase was shifted to 40,000 , a molecular weight similar to that of low affinity [ 3h ] pyrilamine binding sites on undifferentiated cells .
