Specifications Source Biotinylated Human ROR2/NTRKR2 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Val34-Gly403.[Accession | A1L4F5] Molecular Weight The protein has a predicted MW of 44.2 kDa. Due to glycosylation, the protein migrates to 54-65 kDa based on Tris-Bis PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by Tris-Bis PAGE and HPLC Activity ELISA Data: Immobilized Anti-ROR2 Antibody, hFc Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human ROR2, hFc Tag with the EC50 of 6.5ng/ml determined by ELISA. 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℃ for 1 year from date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3 months, -25~-15℃ 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.
