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.
