FcERI / Fc Epsilon RI
FCER1A | Alpha polypeptide | FCE1A | FcERI | Fc Epsilon RI | Fc epsilon RI alpha-chain | Fc-epsilon RI-alpha | IgE Fc receptor subunit alpha
Predicted Molecular Weight
21.9 kDa. DTT-reduced protein migrates as 40-60 kDa due to glycosylation
HEK 293 Cells
Greater than 90% by SDS-PAGE
Measured by its binding ability in a functional ELISA. Immobilized human FCER1A at 2 µg/ml (100 µl/well). The concentration of Human IgE that produces 50% of the optimal binding response is found to be approximately 0.1 - 0.4 µg/ml.
Less than 1.0 EU/µg protein (determined by LAL method).
Lyophilized from PBS, pH 7.4, mannitol or trehalose
Centrifuge the vial before opening. Reconstitute in sterile PBS, pH 7.4 to 50 µg/ml. Do not vortex.
Store lyophilized at -20°C. After reconstitution, aliquot and store at -80°C. Avoid freeze-thaw cycles.
For research use only. Intended for use by laboratory professionals.
This protein carries the LSBio 100% Guarantee.
