Interleukin-2 (IL-2) is a vital cytokine that regulates immune responses by promoting the growth and activation of T-cells, enhancing immune function, and maintaining immune tolerance for immune activation and suppression.

Qkine has optimised the IL-2 manufacture process to produce a highly bioactive protein with excellent lot-to-lot consistency for enhanced experimental reproducibility. Qkine IL-2 is a highly pure 15.5 kDa monomer, animal origin-free (AOF) and carrier-protein-free (CF).

• Highly pure human IL-2 protein (UniProt number: P60568)
