Overview

The IL-2 Secretion Assay - Cell Enrichment and Detection Kit was developed for the sensitive detection as well as the enrichment of murine IL-2-secreting cells.

Detailed product information

Background information

Interleukin-2 (IL-2) is a T cell-derived cytokine known to promote growth and differentiation of T cells and has pleiotropic effects on many other leukocytes. IL-2 is rapidly secreted upon activation by naive T helper cells and certain subsets of memory T cells.

Downstream applications

The Mouse IL-2 Secretion Assay was used to study the sequential production of cytokines by T helper lymphocytes.

Furthermore, it was used for isolation and analysis of IL-2-secreting NKT cells after stimulation with glycolipids.

The IL-2 Secretion Assay has also been used as a highly sensitive read-out system for peptide-specific T cells in TCR transgenic mice.

T cell suppression by CD4

regulatory T cells has been analyzed with the IL-2 Secretion Assay by coculturing responder T cells with regulatory T cells (distinguished by Thy1.1 and Thy1.2 expression) followed by cytokine detection and costaining with Thy1.1.
