Product Properties Synonyms ETGF; TGF-alpha; TGF type 1; TGFA Species Human Source HEK293 Sequence Val40-Ala89 Accession P01135-1 Tag N-hFc Molecular Weight The protein has a predicted MW of 32.9 kDa. Due to glycosylation, the protein migrates to 38-45 kDa based on Bis-Tris PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by Bis-Tris PAGE and HPLC Activity ELISA Data: Immobilized Human TGF-alpha, hFc Tag at 0.2μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Anti-TGF-alpha Antibody, hFc Tag with the EC50 of 6.0ng/ml determined by ELISA SPR Data: Human EGFR, His Tag captured on CM5 Chip via anti-his antibody can bind Human TGF-alpha, hFc Tag with an affinity constant of 0.31 μM as determined in SPR assay. Formulation Lyophilized from 0.22μm filtered solution in 50mM Tris,100mM NaCl (pH 8.0). Normally 8% trehalose is added as protectant before lyophilization.
