Recombinant Human IL-2 R beta&IL-2 R gamma Protein,hFc Tag

Description :
Source Human IL-2 R beta&IL-2 R gamma Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Ala27-Thr240 (IL-2 R beta)&Leu23-Ala262 (IL-2 R gamma).[Accession |P14784(IL-2 R beta)&P31785-1(IL-2 R gamma)] Molecular Weight The protein has a predicted MW of 51.3 kDa (IL-2 R beta)&54.6 kDa (IL-2 R gamma). Due to glycosylation, the protein migrates to 65-70 kDa&80-100 kDa based on Tris-Bis PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by Tris-Bis PAGEandHPLC Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
