| 摘 要： | In recent years we have done a series of observations on the haemopoietic modulation effects oflymphocytes. Now we report here, for the first time, the pulification of a modulating factor (prolif-eration amplifying factor, PAE) with affinity chromatography and HPLC from supernatant conditionedby a lymphoma cell line M12.4.1. RAF exhibits on SDS-PAGE only one band, the molecular weightis about 31,000, the specific activity is 20,000 times that in the conditioned medium. It may providea direct evidence that the B lymphocyte also possesses some haemopoietic modulation effects.
