Cotton Rat IL-2 Antibody

  
  • Species Reactivity
    Cotton Rat
  • Specificity
    Detect cotton rat IL‑2 in direct ELISAs and Western blots. In direct ELISAs, approximately 20% cross-reactivity with recombinant rat IL-2 and recombinant mouse IL-2 is observed and less than 5% cross-reactivity with recombinant human IL-2 and recombinant porcine IL-2 is observed.
  • Source

  • Purification
    Antigen Affinity-purified
  • Immunogen
    E. coli-derived recombinant cotton rat IL‑2
  • Formulation
    Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
  • Endotoxin Level
    <0.10 EU per 1 μg of the antibody by the LAL method.
  • Label
    Unconjugated
Applications
  •  
    Recommended
    Concentration
    Sample
  • Western Blot
    0.1 µg/mL
    Recombinant Cotton Rat IL‑2 (Cys146Tyr) (Catalog # 579-R2)
  • 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 0.1-0.4 µg/mL in the presence of 1.5 ng/mL Recombinant Cotton Rat IL‑2 (Cys146Tyr).
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.
Data Examples
Cell Proliferation Induced by IL‑2 and Neutralization by Cotton Rat IL‑2 Antibody. Recombinant Cotton Rat IL‑2 (Cys146Tyr) (Catalog # 579-R2) stimulates proliferation in the CTLL‑2 mouse cytotoxic T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Cotton Rat IL‑2 (Cys146Tyr) (1.5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Cotton Rat IL‑2 Antigen Affinity-purified Poly­clonal Antibody (Catalog # AF579). The ND50 is typically 0.1-0.4 µg/mL.

Background: IL-2
IL-2 (Interleukin 2) is a critical cytokine in T cell biology. It promotes T cell activation and expansion, the development, maintenance and function of regulatory T cells (Treg), and the differentiation of CD8+ T cells into terminal effector cells and memory cells. IL-2 signals through a receptor complex composed of CD25/IL-2 R alpha, IL-2 R beta, and the Common gamma Chain (gamma c). IL-2 R beta is also a component of the IL-15 receptor complex. Gamma c is also a signaling subunit in the receptors for IL-4, -7, -9, -15, and -21.
  • Long Name:
    Interleukin 2
  • Entrez Gene IDs:
    3558 (Human); 16183 (Mouse); 116562 (Rat); 396868 (Porcine); 280822 (Bovine); 403989 (Canine); 100034204 (Equine); 751114 (Feline); 100302458 (Rabbit)
  • Alternate Names:
    aldesleukin; IL2; IL-2; IL-2lymphokine; interleukin 2; interleukin-2; involved in regulation of T-cell clonal expansion; T cell growth factor; T-cell growth factor; TCGF
