Human IL-2 (Animal-Free Recombinant)

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.
