ICFC - Quality tested

Application Notes:

ELISA Detection1-3 or ELISPOT Detection4-6: The biotinylated JES6-5H4 antibody is useful as a detection antibody for a sandwich ELISA or ELISPOT assay, when used in conjunction with the purified JES6-1A12 antibody as capture antibody and recombinant mouse IL-2 as the standard.
Flow Cytometry8-10: The fluorochrome-labeled JES6-5H4 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify IL-2 -producing cells within mixed cell populations.

Recommended Usage: Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

IL-2 is a potent lymphoid cell growth factor which exerts its biological activity primarily on T cells. Additionally, IL-2 has been found to stimulate growth and differentiation of B cells, NK cells, LAK cells, monocytes, and oligodendrocytes.

Other Names: Interleukin-2, T cell growth factor (TCGF), Eosinophil differentiation factor (EDF), Killer cell helper factor (KHF), Macrophage-activating factor for cytotoxicity I (MAF-C I), Thymocyte differentiation factor (TDF)
Structure: Cytokine; 15-30 kD (Mammalian)
Regulation: Upregulated by NFAT; downregulated by TCF-8, CIF (colostrum inhibitory factor)
Cellular Sources: T cells
Cellular Targets: T cells, B cells, NK cells, LAK cells, monocytes, macrophages, oligodendrocytes
Receptors: High affinity heterotrimer of IL-2Rα/β/γ, intermediate affinity homodimer IL-2Rα (CD25; p55; Tac) and heterodimer IL-2Rβ (CD122)/γ; γ-subunit (CD132) in common with IL-4R, IL-7R, IL-13R, IL-15R
Bioactivity/Activities: Proliferation of T lymphocytes, B cells, anti-inflammatory, hematopoiesis, tumor surveillance
