Fc fragment of IgE, high affinity I, receptor for; alpha polypeptide (FCER1A) binds to the Fc region of immunoglobulins epsilon. FCER1A is a high affinity receptor. In addition FCER1A is responsible for starting the allergic response. Binding of allergen to receptor-bound IgE leads to cell activation and the release of mediators such as histamine which is responsible for the manifestations of allergy. This receptor is contains of an alpha subunit, a beta subunit, and two gamma subunits. FCER1A stands for the alpha subunit. Among the diseases associated with FCER1A are mast-cell leukemia, and allergic asthma.

FCER1A Human Recombinant produced in E.Coli is a non-glycosylated polypeptide chain containing 201 amino acids.
FCER1Ais fused to a 6 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques.

Escherichia Coli.

Sterile Filtered colorless solution.

1x PBS, pH-7.4, 50mM Arginine and 0.05% NaN₃.

The Recombinant FCER1A protein although stable at 4°C for 1 week, should be stored below
-18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
