Measured by its ability to neutralize IL‑2-induced proliferation in the CTLL‑2 mouse cytotoxic T cell line. Gearing, A.J.H. and C.B. Bird (1987) in Lymphokines and Interferons, A Practical Approach. Clemens, M.J. et al. (eds): IRL Press. 276. The Neutralization Dose (ND50) is typically 0.125-0.75 µg/mL in the presence of 1 ng/mL Recombinant Mouse IL‑2.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Cell Proliferation Induced by IL‑2 and Neutralization by Mouse IL‑2 Antibody. Recombinant Mouse IL‑2 (Catalog # 402-ML) stimulates proliferation in the CTLL‑2 mouse cytotoxic T cell line in a dose-dependent manner (orange line), as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Mouse IL‑2 (1 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse IL‑2 Monoclonal Antibody (Catalog # MAB702). The ND50 is typically 0.125-0.75 µg/mL.

IL-2 is a cytokine that stimulates the growth and differentiation of B cells, T cells, NK cells, and monocyte/macrophages. It functions through the heterotrimeric IL-2 receptor comprising alpha, beta, and gamma chains.
R&D Systems personnel manually curate a database that contains references using R&D Systems products.
The data collected includes not only links to publications in PubMed,
but also provides information about sample types, species, and experimental conditions.
The reconstitution calculator allows you to quickly calculate the volume of a reagent to reconstitute your vial. Simply enter the mass of reagent and the target concentration and the calculator will determine the rest.
