IL-2 stands out as a potent immunoregulatory lymphokine generated by T cells following antigenic or mitogenic stimulation. Its signaling through IL-2R is critical for T cell proliferation and other vital immune response activities. IL-2 plays a pivotal role in stimulating the growth and differentiation of various immune cells like B cells, NK cells, lymphokine-activated killer cells, monocytes, macrophages, and oligodendrocytes.
The recombinant Human IL-2 is a 15.5 kDa protein composed of 134 amino acid residues, featuring one intrachain disulfide bond.
