Product Properties Alternative Names DRT, ERK, HEK5, TYRO5, CAPB, EK5, EPHT3, PCBC, Cek5, EphB2, EPHT3MGC87492, Nuk, Qek2, Sek3 Species Cynomolgus Expression Sequence Val19-Pro542 Accession A0A7N9CQH5 Tag C-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 59.09 kDa. Due to glycosylation, the protein migrates to 65-75 kDa based on SDS-PAGE result. Purity > 95% as determined by SDS-PAGE and HPLC. Endotoxin < 1.0 EU per μg by the LAL method. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Biological Activity 【ELISA Data】 Immobilized Cynomolgus EPHB2, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Anti-EPHB2 Antibody, hFc Tag with the EC50 of 8.3ng/ml determined by ELISA. Reconstitution Method Before opening, centrifuge briefly. Reconstitute the lyophilized protein with distilled water to a concentration exceeding 100 μg/mL. Aliquot after initial reconstitution to avoid repeated freeze-thaw cycles. Features High purity, high activity, low endotoxin, high batch-to-batch consistency Storage Store at -25 ~ -15℃, valid for 1 year after receipt. After reconstitution, store at -85 ~ -65℃ under sterile conditions, valid for 3 months.
