Specifications Synonyms FcERI;Fc-epsilon RI-alpha; FCER1A Source Mouse Fc Epsilon RI alpha/FCER1a Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Ala24-Gln204.[Accession | P20489] Molecular Weight The protein has a predicted MW of 47.7 kDa. Due to glycosylation, the protein migrates to 68-72 kDa based on SDS-PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Formulation Lyophilized from 0.22μm 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 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage The product should be stored at -25~-15°C for 1 year from date of receipt. 2-7 days, 2 ~ 8°C under sterile conditions after reconstitution. 3 -6 months, -85~-65°C under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles. Note 1.Please operate with lab coats and disposable gloves, for your safety. 2.This product is for research use only.
