          Human IL-2 receptor alpha (IL-2 R alpha ), also known as Tac antigen and as CD25, was initially identified as a 55 kDa membrane glycoprotein that is capable of binding IL2. By itself, IL-2 R alpha binds IL-2 with low affinity.

          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.

          Lyophilized from 0.22μm 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.
