*The Sample Volume represented is based on the amount of sample incorporated into the reaction after taking into account the assay’s minimum required dilution for a given matrix. Serial dilution may be necessary to achieve some of the final sample volumes represented.

Product Summary

Simple Plex assay for the detection of human Interleukin 2 (IL-2) in cell culture supernatant (CCS), serum and plasma (EDTA/Heparin).

Precision

Intra-Assay Precision (Precision within an assay) Each control was tested 16 times in one assay

Inter-Assay Precision (Precision between assays) Replicates of each control were tested in multiple assays performed by at least three technicians using two lots of reagents

Cell Culture Supernates, Serum, EDTA Plasma, Heparin Plasma

	Intra-Assay Precision		Inter-Assay Precision
Sample	1	2	1	2
n	16	16	8	8

Background: IL-2

IL-2 (Interleukin 2) is a critical cytokine in T cell biology. It promotes T cell activation and expansion, the development, maintenance and function of regulatory T cells (Treg), and the differentiation of CD8+ T cells into terminal effector cells and memory cells. IL-2 signals through a receptor complex composed of CD25/IL-2 R alpha, IL-2 R beta, and the Common gamma Chain (gamma c). IL-2 R beta is also a component of the IL-15 receptor complex. Gamma c is also a signaling subunit in the receptors for IL-4, -7, -9, -15, and -21.
