      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.
      
			      		
		
      
		
      
			
			
      Purity
      
			      		
			
			
      > 95% as determined by SDS-PAGE and HPLC.
      
			      		
		
      
		
      
			
			
      Endotoxin
      
			      		
			
			
      <1.0 EU per 1μg of the protein by the LAL method.
      
			      		
		
      
		
      
			
			
      Formulation
      
			      		
			
			
      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.
