Active Recombinant Human FCER1A Protein (26-205aa), C-His tagged

• Cat.No.: FCER1A-25H
• Product Overview: Recombinant human Fc epsilon RI alpha/FCER1A (26-205 aa), fused to His-tag at C-terminus, was expressed in HEK293 cell and purified by using conventional chromatography techniques.

Specification

• Description: The immunoglobulin epsilon receptor (IgE receptor) is the initiator of the allergic response. When two or more high-affinity IgE receptors are brought together by allergen-bound IgE molecules, mediators such as histamine that are responsible for allergy symptoms are released. This receptor is comprised of an alpha subunit, a beta subunit, and two gamma subunits. The protein encoded by this gene represents the alpha subunit.
