Quantification
In this sandwich ELISA, Mouse Interleukin 2,IL-2 ELISA kit in the sample is captured between a pre-coated capture antibody and a detection antibody. Signal intensity is proportional to analyte concentration. Quantification uses a standard curve fitted with Curve Expert software, covering 3.9 pg/ml-250 pg/ml with a minimum detectable dose of 0.975 pg/ml.
This kit provides quantitative measurement of interleukin-2 (IL-2) in mouse samples, supporting research into T cell activation, proliferation, and immune regulation. Because IL-2 is produced transiently and at low concentrations following T cell receptor engagement, detecting it requires an assay calibrated for the picogram-level abundances typical of both *in vivo* and *in vitro* immunological models.
Detection Range: The 3.9–250 pg/ml range spans the concentrations expected in mouse serum during acute immune responses and in supernatants from antigen- or mitogen-stimulated splenocyte cultures. Most resting or mildly stimulated samples fall within range without dilution, while strongly activated cultures may require a simple pre-dilution step.
- Data show that after tumor necrosis factor alpha-induced protein 8 like-2 (TIPE2) gene was down-regulated, the expression of the CD69 antigen was increased, and the proliferation of T lymphocytes and the secretion of cytokines IL-2 and IFN-gamma were enhanced. PMID: 27363266
- WASp knockout mice controlled growth of A20 lymphoma cells that naturally produced IL-2. PMID: 27477778

- in vivo targeting of the TNF superfamily receptor TNFRSF25 using the TL1A-Ig fusion protein, along with IL-2, resulted in transient but massive Treg expansion in donor mice; transplantation of Treg-expanded donor cells facilitated transplant tolerance without GVHD, with complete sparing of graft-versus-malignancy. PMID: 28219835
- IL-2 signalling is essential to prevent deletion of CD4SP CCR7+ Helios+ thymocytes at a later developmental stage than Card11 is required to prevent deletion. The deletion prevented by IL-2 signalling occurs in a Foxp3-independent manner. PMID: 28362433
- studies revealed a new epigenetic pathway in the control of IL-2 production in systemic lupus erythematosus whereby low levels of miR-200a-3p accumulate the binding of the ZEB1-CtBP2 complex to the IL-2 promoter and suppress IL-2 production PMID: 28438897
- data suggest that the use of Golgi transport inhibitors results in an underestimation of the presence of type 2 cytokine-secreting cells and highlight IL-2 as a critical component in optimal cytokine production by Th2 and Th9 cells in vitro and in vivo PMID: 28468971
- Suppression of IL-12p70 formation by IL-2 or following macrophage depletion causes T-cell autoreactivity leading to CNS demyelination in HSV-1-infected mice. PMID: 28542613
- results show that IL-23 accounts for the main aspects of human and murine lupus including the expansion of double negative T cells, decreased IL-2, and increased IL-17 production PMID: 28646040
- a significant increase in plasma levels of IL-2, IFN-g and TNF-g was revealed as assessed by ELISA. In conclusion, the results of the present study indicate that MENK has a cytotoxic effect on B16 melanoma cells in vitro and in vivo, and suggest a potential mechanism for these bioactivities. PMID: 28849104
- These studies demonstrate that Th1 CD4(+) T cells require IL-2 for lung T resident memory cell development. PMID: 28948612
- Data show that PTEN plays a key role in Th17 cell differentiation by blocking IL-2 expression. PMID: 29018045
- Each mutation decreased STAT5 binding and altered IL-2-induced Il2ra gene expression, revealing that individual elements within the superenhancer were not functionally redundant and that all were required for normal gene expression. PMID: 29078395
- this report, we elucidated the unsolved mechanism of the anti-cancer effect of curcumin by identifying IL-2 as a direct molecular target. Curcumin, as a small molecule IL-2 modulator, has the potential to be used to treat IL-2 related pathologic conditions. PMID: 29127008
- Deleting IL-2 in CD11c(high)MHCII(+) cells induces spontaneous colitis resembling human inflammatory bowel disease. PMID: 29549257
- Because IL-2 production was limited to cells receiving the strongest T cell receptor (TCR) signals, a direct link between TCR-signal strength, IL-2 production, and T cell fate determination has been established. PMID: 30213884
