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.

For research use only (RUO). Not intended for diagnostic or therapeutic purposes. Validated in mouse serum, plasma, tissue homogenates, cell culture supernates matrices only.
Description

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.

Alternative Names
Il2 ELISA kit; Il-2Interleukin-2 ELISA kit; IL-2 ELISA kit; T-cell growth factor ELISA kit; TCGF ELISA kit
Function
Produced by T-cells in response to antigenic or mitogenic stimulation, this protein is required for T-cell proliferation and other activities crucial to regulation of the immune response. Can stimulate B-cells, monocytes, lymphokine-activated killer cells, natural killer cells, and glioma cells.

  13. 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

  20. 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
  21. 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
  22. Deleting IL-2 in CD11c(high)MHCII(+) cells induces spontaneous colitis resembling human inflammatory bowel disease. PMID: 29549257
  23. 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
