Quantification

In this sandwich ELISA, interleukin 15 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 3.12 pg/mL-200 pg/mL with a minimum detectable dose of 1.56 pg/mL.

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

This ELISA kit provides quantitative measurement of interleukin-15 (IL-15) in human serum, plasma, and tissue homogenates, supporting research into its roles in NK cell development, CD8+ T cell homeostasis, and inflammatory signaling. Because IL-15 circulates at exceptionally low concentrations and is often bound to IL-15Rα in trans-presentation complexes, accurate quantification demands both high sensitivity and carefully validated detection parameters.

Detection Range: The 3.12–200 pg/mL range aligns with reported circulating IL-15 levels in healthy individuals (typically <10 pg...[NOT FOUND ON SOURCE URL]

Function
Cytokine that stimulates the proliferation of T-lymphocytes. Stimulation by IL15 requires interaction of IL15 with components of the IL2 receptor, including IL2RB and probably IL2RG but not IL2RA. In neutrophils, stimulates phagocytosis probably by signaling through the IL15 receptor, composed of the subunits IL15RA, IL2RB and IL2RG, which results in kinase SYK activation.
