In rat basophilic leukemia cells (RBL-2H3), a tumor analogue of mast cells, the aggregation of IgE receptors initiates increase in the intracellular concentration of calcium ([Ca2+]i), monitored with the fluorescent Ca probe fura-2, and finally results in histamine secretion. In
The capacity of the stomach to participate in anaphylaxis induced by the hapten N,N'-di-2,4,dinitrophenyllysine (di-DNP-lysine) was examined in BDF1 female mice immunized with dinitrophenylated Ascaris suum extract. Immunized animals underwent laparotomy and nontraumatic pyloric occlusion using a microvascular clamp. Following
We developed a novel trifunctional carrier molecule for the synthesis of hapten-fluorophore conjugates as reporter molecules in immunoassays. This carrier eliminates some of the disadvantages associated with currently used fluorophore-labeling procedures including high nonspecific binding. The backbone of the carrier
Journal of immunological methods, 138(2), 245-255 (1991-04-25)
The influence of the epitope density of the antigen on antibody affinity values determined by fluid- and solid-phase immunoassays was assessed. The affinity of the interaction of a panel of monoclonal anti-DNP antibodies of different affinities (as determined by equilibrium
Clinical and experimental immunology, 64(1), 125-135 (1986-04-01)
Thymus-independent (TI) and thymus-dependent (TD) primary immune responses were measured in 67 controls and 13 bone marrow transplant (BMT) recipients treated with cyclosporine (CSP) by immunizing with a synthetic antigen (DNP-Ficoll) and keyhole limpet haemocyanin (KLH). DNP-Ficoll induced similar TI
