Abstract
Passive transfer of homograft immunity was successfully achieved by injection of the supernatant obtained from tissue-sensitized lymphoid cells disrupted by sonic vibration. The effective substance destroyed specific skin homografts within 6 days but did not reject non-specific skin grafts in this time. No evidence of transferred antigen or of transfer factor was found when the effective material was passed to irradiated recipients carrying test grafts. By a variety of physiochemical procedures the "soluble substance" behaved like a gamma globulin and was considered to be a transplantation antibody.
