Recombinant Biotinylated Human FGF21 Protein,mFc-Avi Tag

Description :
Synonyms FGF-21; PRO10196;UNQ3115; Source Biotinylated Human FGF21 Protein is expressed from HEK293 with mFc (IgG1) tag and Avi tag at the N-Terminus. It contains His29-Ser209.[Accession | Q9NSA1] Molecular Weight The protein has a predicted MW of 46.9 kDa. Due to glycosylation, the protein migrates to 55-65 kDa based on SDS-PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity ELISA Data: Immobilized Biotinylated Human FGF21, mFc Tag at 5g/ml (100l/well) on the streptavidin precoated plate (5g/ml). Dose response curve for Human Beta Klotho, His Tag with the EC50 of 63.9ng/ml determined by ELISA. Formulation Lyophilized from 0.22m 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 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
