Single cell suspensions of rat lymphoid and nonlymphoid tissues were fractionated on discontinuous gradients of bovine serum albumin into high density and low density subfractions. In general, accessory activity required for responses of periodate-treated T lymphocytes was recovered only in a low density population containing a small percent of the total(More)
Transfer of specific immunity was investigated in a group of 28 paediatric and adult leukaemia patients during the first 100 d after allogeneic bone marrow transplantation (BMT). These patients and/or their donors were immunized 7-13 d before transplantation with the recall antigen tetanus toxoid (TT) and the neo-antigen Helix pomatia haemocyanin (HPH). The(More)
A rapid recovery of specific humoral immunity in the recipient of an allogeneic bone marrow transplantation (BMT) can be observed after immunization of the donor before graft sampling. This has been attributed to transfer of specific immunity from donor to recipient. However, to maintain the concept of transfer the origin of the antibody producing cells in(More)
A dot-immunobinding assay on nitrocellulose membranes has been developed for the quantification of human IgG subclasses using subclass-specific monoclonal antibodies. The advantages of this technique can be summarized as follows: (1) possibility of rapid semi-quantitative evaluation and/or precise quantitation from the same dot-pattern; (2) simple procedure(More)
