Recombinant Human IL-2 R alpha/CD25 Protein, His-Avi Tag

Description :
Synonyms CD25; IDDM10; IL-2 R alpha; IL2R; IL2RA; p55; TCGFR Uniprot No. P01589 Source Recombinant Human IL-2 R alpha/CD25 Protein is expressed from HEK293 cell with His tag and Avi tag at the C-terminal. It contains Glu22-Cys213. Molecular Weight The protein has a predicted MW of 24.6 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result. Purity > 95% as determined by SDS-PAGE and HPLC. Endotoxin 1.0EU per 1g of the protein by the LAL method. Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Dissolve lyophilized protein with sterile water to ensure the concentration is greater than 100 ug/mL.
