Basophil activation test is a potent tool for the detection of IgE-dependent allergies in vitro. Here, an optimized protocol for basophil activation test is used to investigate drug hypersensitivity. A method for the efficient production of covalent drug-protein conjugates and their physicochemical characterization is described.

Here we present the mediator release assay, using a rat basophilic leukemia cell line transfected with the human IgE receptor, to simulate the degranulation of effector cells typically observed in type 1 allergic reactions. This method investigates the biological activity of allergens in a highly sensitive, reproducible, and tailorable manner.
