متن کاملRecovery of Antibody Activity from Inactive Hybrids
Globulin molecules can be reconstituted from th e separated heavy (H) and light (L) chains of specifically purified antihapten antibody (1, 2). When the chains are derived from the same rabbit, antibody activity is recovered (1, 3, 4). Hybrid molecules of chains from different rabbits have been found to show only questionable activity (5, 6). Since the chains in hybrids are not linked by covale...
متن کاملTRANSPLANTATION IMMUNITY, IMMUNOLOGICAL TOLERANCE, AND CHICKEN x TURKEY INTERSPECIFIC HYBRIDS.
Although a high degree of tolerance of homografts of skin and other tissues can consistently be induced in a variety of avian and mammalian species by exposure of embryonic or neonatal hosts to homologous cells,1 2 nearly all attempts to confer tolerance in respect of grafts of heterologous origin have given very disappointing results in terms of the degrees of unresponsiveness obtained. Howeve...
