| Background Information | Human Interleukin-2 (IL-2) is a recombinant cytokine belonging to the common γ-chain family, critically involved in the activation, proliferation, and survival of T cells. IL-2 is produced primarily by activated CD4⁺ T cells and plays a central role in regulating immune responses, making it essential for immunology research, cell-therapy manufacturing, and T-cell expansion protocols. |
