A Human‐Human Monoclonal Anti‐D by Direct Fusion with a Lymphoblastoid Line1

Abstract
The human lymphoblastoid cell line W1-L2-729 HF2 has been fused with B cells from a plasmaphoresed anti-D donor immunized with D+ cells. A stable monoclonal antibody-producing cell line has been produced which yields culture supernatant of good titre without the need for concentration. The production and use of this reagent as an alternative Rh D typing reagent for use by saline and enzyme manual tests and automated tests in a Technicon 16C machine is discussed. Du red cells are detected in enzyme enhanced tests.
