Allergen-specific Immunoglobulin E (IgE) determination lies at the heart of diagnosis of sensitization to food and other allergens. In the past few years, reporter systems capable of detecting the presence of allergen-specific IgE have been developed by several labs. These rely on humanized rat basophil leukemia cell lines stably transfected with reporter genes such as firefly luciferase. In this chapter, we describe protocols for the use of the RS-ATL8 cell line (IgE cross-linking-induced luciferase expression; EXiLE) in 96-well and 384-well formats. We also describe optional treatment steps for enveloped virus and complement inactivation.
