简单描述
The JES6-5H4 monoclonal antibody specifically binds to mouse interleukin-2 (IL-2), a multifunctional cytokine that plays pivotal roles in immunity and tolerance. It is produced by activated T cells and affects the activation, growth, proliferation and/or differentiation of various cell types including T and B lymphocytes and their precursors, LAK cells, NK cells, and monocytes/macrophages. IL-2 mediates its biological activities by binding to IL-2 receptor complexes. The intermediate affinity IL-2R is comprised of IL-2Rβ (CD122) and common gamma chain (γc; CD132) subunits, whereas the high-affinity IL-2R is comprised of IL-2Rα (CD25), IL-2Rβ, and γc subunits. The JES6-5H4 monoclonal antibody binds to IL-2 and neutralizes its biological activity.

PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Expression of IL-2 by stimulated CD4+ and CD4- BALB/c spleen cells. Splenocytes from 6 month old BALB/c mice were stimulated for 5 hours with hamster anti-mouse CD3 (2 µg/ml final concentration; clone 145-2C11, Cat. No. 553057) and hamster anti-mouse CD28 (2 µg/ml final concentration; clone 37.51, Cat. No. 553294) antibodies in the presence of GolgiStop™ (2 µM final concentration; Cat. No. 554724). The splenocytes were harvested, stained with 0.06 µg of FITC-conjugated rat anti-mouse CD4 (FITC-RM4-5, Cat. No. 553047), fixed, permeabilized, and subsequently stained with 0.25 µg of PE anti-mouse IL-2 (Cat. No. 554428) (left panel). To demonstrate specificity, PE-JES6-5H4 staining was blocked by each of the following: 1) preincubation of the conjugated antibody with recombinant mouse IL-2 (0.25 µg, Cat. No. 550069; middle panel) and by 2) preincubation of the fixed/permeabilized cells with unlabelled JES6-5H4 mAb (5.0 µg; Cat. No. 554425) prior to staining with PE-JES6-5H4 (right panel). The quadrant markers for the bivariate dot plots were set based on the autofluorescence controls and verified using the recombinant cytokine blocking and unlabelled antibody blocking specificity controls.
