Specifications Synonyms ErbB3; ErbB-3; HER3; HER3c-erbB-3; LCCS2; MDA-BF-1; MGC88033; p180-ErbB3; p45-sErbB3; p85-sErbB3; ERBB3 Source FITC-Labeled Human Her3/ErbB3 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Ser20-Thr643.[Accession | P21860-1] Source The protein has a predicted MW of 71.6 kDa. Due to glycosylation, the protein migrates to 72-75 kDa based on SDS-PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by SDS-PAGE Formulation Lyophilized from 0.22 μm filtered solution in HER-HM403F. 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 1.The product should be stored at -25~-15℃ for 1 year from date of receipt. 2.2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3.3 -6 months, -85~-65℃ under sterile conditions after reconstitution. 4.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.
