Product Description	Recombinant Human IgE Protein is expressed from HEK293 with His and Avi tag at the C-Terminus.It contains Cys209-Lys428.
Product Background	Immunoglobulin E (IgE) is well known for its role in allergic disease, the manifestations of which are mediated through its two Fc receptors, FcεRI and CD23 (FcεRII). IgE and its interactions with these receptors are therefore potential targets for therapeutic intervention, and exciting progress has been made in this direction. Furthermore, recent structural studies of IgE-Fc, the two receptors, and of their complexes, have revealed a remarkable degree of plasticity at the IgE-CD23 interface and an even more remarkable degree of dynamic flexibility within the IgE molecule.
Product Category	Recombinant Protein / Antibody discovery

Protein	IgE
Synonyms	Ig epsilon chain C region;IgE
Accession	P01854-1
Species	Human

Amino Acid Range	Cys209-Lys428
Molecular Weight	The protein has a predicted MW of 27.8 kDa. Due to glycosylation, the protein migrates to 30-35 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human IgE, His Tag at 0.5ug/ml (100ul/well) on the plate. Dose response curve for Anti-IgE Antibody, hFc Tag with the EC50 of 7.0ng/ml determined by ELISA. See testing image for detail.
Product Tag	C-His-Avi
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
