| 反应种属 | Mouse |
| 应用 | Western Blot,Neutralization |
| 目标/特异性 | Detects mouse IL-2 in direct ELISAs and Western blots. In direct ELISAs, approximately 10% cross-reactivity with recombinant rat IL‑2 and recombinant cotton rat IL‑2 is observed and less than 2% cross-reactivity with recombinant human IL‑2, recombinant canine IL‑2, recombinant feline IL‑2, recombinant equine IL‑2, recombinant bovine IL‑2, and recombinant porcine IL‑2 is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Neutralization: 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 0.1-0.3 µg/mL in the presence of 2 ng/mL Recombinant Mouse IL‑2. |

| 背景 | 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. |

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 ND50 is typically 0.1-0.3 µg/mL. |
