Mouse IL-2 Antibody Summary
Accession # P04351
This antibody functions as an ELISA detection antibody when paired with Rabbit Anti-Mouse IL‑2 Monoclonal Antibody(Catalog # MAB4022).
This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Mouse IL-2 DuoSet ELISA Kit (Catalog # DY402) for convenient development of a sandwich ELISA or the Mouse IL-2 Quantikine ELISA Kit (Catalog # M2000) for a complete optimized ELISA.
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). Proliferation elicited by Recombinant Mouse IL‑2 (2 ng/mL) is neutralized (green line) by increasing concentrations of Mouse IL‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-402-NA). The ND50is typically 0.1-0.3 µg/mL.

Interleukin-2 (IL-2) is an O-glycosylated four alpha -helix bundle cytokine that has potent stimulatory activity for antigen-activated T cells. It is expressed by CD4+ and CD8+ T cells, gamma δ T cells, B cells, dendritic cells, and eosinophils. Mature mouse IL-2 shares 56% and 73% aa sequence identity with human and rat IL-2, respectively. It shows strain-specific heterogeneity in an N-terminal region that contains a poly-glutamine stretch. Mouse and human IL-2 exhibit cross-species activity. The receptor for IL-2 consists of three subunits that are present on the cell surface in varying preformed complexes. The 55 kDa IL-2 R alpha is specific for IL-2 and binds with low affinity. The 75 kDa IL-2 R beta, which is also a component of the IL-15 receptor, binds IL-2 with intermediate affinity. The 64 kDa common gamma chain gamma c/IL-2 R gamma, which is shared with the receptors for IL-4, -7, -9, -15, and -21, does not independently interact with IL-2. Upon ligand binding, signal transduction is performed by both IL-2 R beta and gamma c. IL-2 is best known for its autocrine and paracrine activity on T cells. It drives resting T cells to proliferate and induces IL-2 and IL-2 R alpha synthesis. It contributes to T cell homeostasis by promoting the Fas-induced death of naïve CD4+ T cells but not activated CD4+ memory lymphocytes. IL-2 plays a central role in the expansion and maintenance of regulatory T cells, although it inhibits the development of Th17 polarized cells. Thus, IL-2 may be a key cytokine in the natural suppression of autoimmunity.
