应用备注
-
ELISA Standard: Recombinant mouse IL-2 is useful as a quantitative standard for measuring mouse IL-2 protein levels in an IL-2 specific sandwich ELISA with the purified JES6-1A12 antibody (Cat. No. 554424) as a capture antibody and the biotinylated JES6-5H4 antibody (Cat.No. 554426) as the detection antibody. To obtain linear standard curves, doubling dilutions of this mouse IL-2 standard from ~2,000 to 15 pg/ml should be included in each ELISA plate.
Note: This ELISA pair is recommended primarily for measuring cytokine from experimental cell culture systems. These ELISA reagents are not recommended for assaying serum or plasma samples. For measuring mouse IL-2 in serum or plasma the mouse IL-2 BD OptEIA™ Set (Cat. No. 555148) is specially formulated and recommended. -

背景
- Interleukin-2 (IL-2) is a cytokine which was first described and characterized based upon its potent ability to modulate lymphocyte reactivity and promote long term in vitro culture of antigen-specific effector T lymphocytes. It is responsible for the activities previously ascribed to T cell growth factor, thymocyte stimulating factor, helper-factor and T cell replacing factor, to name a few. IL-2 has also been reported to act on neuronal cells. Mouse IL-2 is a 17.2 kD protein containing 149 amino acid residues.
