A MODEL SYSTEM FOR DETERMINING HISTOCOMPATIBILITY IN MAN*

Abstract
A model system for studying histocompatibility in man has been presented, which utilizes active immunization of an indifferent recipient as a means of evaluating the number of antigens shared by a prospective donor-recipient pair. This system is designed to detect subtle genetic compatibility between two individuals that would certainly be missed if cross-grafting alone were carried out. The practical utilization of such a system in the field of human homotransplantation has been presented.
