title: Isolation of six monoclonal alloantibodies against rat histocompatibility antigens: clonal competition.
abstract: We describe the isolation of six clones and some variant derivatives of rat x mouse hybrid myelomas secreting alloantibody against antigens of the rat major histocompatibility complex. Very large numbers of active hybrids were obtained but many were lost early in the post-fusion period; evidence is presented for rapid selective processes operating in uncloned complex hybrid cultures. The results suggest that the secretion of specific immunoglobulin chains is as stable a function in rat x mouse hybrid myelomas as in mouse x mouse hybrid myelomas.
