Product Properties Alternative Names CD44, CDw44, Epican, ECMR-III, LHR, MDU2, MDU3, MIC4, PGP-I, CSPG8, HCELL, HUTCH-I, IN, MC56 Species Cynomolgus Expression Sequence Gln21-Pro220 & Gln387-Ala428 Accession A0A2K5VJE0 Tag C-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 27.77 kDa. Due to glycosylation, the protein migrates to 45-70 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 CD44, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-CD44 Antibody, hFc Tag with the EC50 of 3.8ng/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.
