AlphaLISA High Performance Biotin-Free Human IL-2 Detection Kit, 500 Assay Point

The AlphaLISA High Performance (HP) Biotin-Free Human IL-2 Detection Kit is designed for the quantitative determination of human IL-2 in serum, buffered solution, or cell culture medium using a homogeneous (no wash steps, no separation steps) assay. This kit is the new and improved version of part number AL333,biotin-free interleukin-2 detection kit. Interleukin 2 (IL-2), formerly known as T-cell growth factor (TCGF), is a 15 kDa immunoregulatory lymphokine produced by lectin- or antigen-activated T cells and capable of inducing the thymic expansion of recently activated antigen-specific T lymphocytes. However, since T-cell immunity can be elicited to various agents in the absence of IL-2 in vivo, it is currently thought that the main non-redundant activity of this cytokine is the induction of the suppressor function of CD4+CD25+ regulatory T cells (Treg) in peripheral lymph nodes to ensure suppression of autoreactive T cells that escape negative selection. Moreover, studies sugge
