Product Description

Recombinant human IgE to be used as reference for IgE concentration measurements in biological samples (ELISA; FACS). IgE (SUS-11) recognizes the human high affinity IgE receptor (FcRI), the human low affinity IgE receptor (CD23) and does not interact with the corresponding IgE receptors of other species. It can be used as functional reagent in mast cell / basophil cellular assays, e.g. for controlled sensitization of such cells and subsequent cross-linking with either anti-human IgE mAbs like mAb LE27 or a specific recombinant cross-linking agent.
