目标/特异性 | Detects porcine IL‑2 in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 40% cross-reactivity with recombinant human IL-2 is observed and less than 1% cross-reactivity with recombinant mouse IL-2 and recombinant rat IL-2 is observed. |
使用方法 | Western Blot: 0.1 µg/mL Immunocytochemistry: 5-15 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 0.25-0.8 µg/mL in the presence of 2 ng/mL Recombinant Porcine IL‑2. |

背景 | Interleukin 2 was initially identified as a T cell growth factor that is produced by T cells following activation by mitogens or antigens. Since then, it has been shown that in addition to its T cell growth factor activity, IL-2 can also stimulate the growth and differentiation of B cells, natural killer (NK) cells, lymphocyte activated killer (LAK) cells, monocytes/macrophages and oligodendrocytes. Mature porcine and human IL-2 share approximately 72% amino acid sequence identity.The biological activity of IL-2 is mediated by the binding of IL-2 to cell surface receptor complexes. The functional high-affinity receptor of IL-2 is composed of three distinct polypeptide chains, the IL-2 receptor alpha, beta and gamma subunits. The intermediate-affinity IL-2 receptor complex, which lacks the alpha subunit, but contains both the beta and gamma subunits, is also capable of transducing the IL-2 signal. In T cells, the beta and gamma subunits are shared with the IL-15 receptor complex. The gamma chain of the IL-2 receptor complex is also a subunit of IL-4, IL-7, and IL-9 receptor complexes. |

Cell Proliferation Induced by IL‑2 and Neutralization by Porcine IL‑2 Antibody. Recombinant Porcine IL‑2 (Catalog # 652-P2) stimulates proliferation in the CTLL‑2 mouse cytotoxic T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Porcine IL‑2 (2 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Porcine IL‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF652). The ND50 is typically 0.25-0.8 µg/mL. | |
IL‑2 in Porcine PBMCs. IL‑2 was detected in immersion fixed porcine peripheral blood mononuclear cells treated with calcium ionomycin and PMA using Goat Anti-Porcine IL‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF652) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.
