Product Name :
Recombinant Human Ephrin-A4/EFNA4 Protein,hFc Tag
Description :
Synonyms LERK-4; Ephrin A4;Ephrin-A4; EPLG4 Source Human Ephrin-A4/EFNA4 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Leu26-Gly171.[Accession | P52798-1] Molecular Weight The protein has a predicted MW of 43.1 kDa. Due to glycosylation, the protein migrates to 50-60 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 Human EphA7, His Tag at 1g/ml (100l/Well) on the plate. Dose response curve for Human Ephrin-A4, hFc Tag with the EC50 of 7.8ng/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.
