Product Description	Recombinant Biotinylated Human IL-2 Protein is expressed from HEK293 with His tag and Avi tag at the C-terminus.It contains Ala21-Thr153.
Product Background	Interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15,5 - 16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 has essential roles in key functions of the immune system, tolerance and immunity, primarily via its direct effects on T cells.
