Product Summary

The Quantikine Human IL-2 Immunoassay is a 4.5 hour solid phase ELISA designed to measure IL-2 levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human IL-2 and antibodies raised against recombinant human IL-2. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural human IL-2 showed dose response curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human IL-2

Recovery

The recovery of human IL-2 spiked to three levels throughout the range of the assay was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=5) 101 96-107
Citrate Plasma (n=5) 105 98-111
EDTA Plasma (n=5) 118 104-139
Heparin Plasma (n=5) 109 94-129
Serum (n=5) 99 89-114

Linearity

To assess the linearity of the assay, five samples were spiked with high concentrations of IL-2 in various matrices and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: IL-2

Interleukin 2 (IL-2), also known as T cell growth factor (TCGF), is a 15-18 kDa variably glycosylated alpha -helical polypeptide that is a member of the Common gamma Chain ( gamma c) cytokine family (1-4). It exists as a monomer and has a notably short half-life (< 30 minutes) (1). Human IL-2 is synthesized as a 153 amino acid (aa) precursor that contains a 20 aa signal sequence plus a 133 aa mature region (5, 6). The mature region is alpha -helical in nature, and contains one utilized O-linked glycosylation site at Thr3 plus three cysteines, two of which form an intrachain disulfide bond that is essential for activity (7). Mature human IL-2 shares 73%, 66%, 78% and 97% aa identity with canine, rat, feline and rhesus monkey IL-2, respectively. Although human IL-2 shares only approximately 60% aa identity with the highly polymorphic mouse IL-2, human IL-2 is known to be active on mouse IL-2 responsive cells. Cells reported to secrete IL-2 include gamma δ T cells (8), activated conventional CD4+ and CD8+ T cells (1, 9), neurons (10, 11), microglia (12), and hematopoietic stem cells (13). 

The receptor for IL-2 (IL-2 R) is composed of three subunits, the 55 kDa CD25/IL-2 R alpha chain, the 70 kDa IL-2 R beta chain, and the 65 kDa Common gamma Chain (1, 3). IL-2 first binds to CD25, the binary complex then recruits IL-2 R beta and gamma c to form the quaternary signaling complex (1, 14). In addition to IL-2, IL-2 R beta is used by IL-15 in its quaternary signaling complex. gamma c also serves as a signaling receptor for IL-4, -7, -9, -15, and -21 (1, 3). 
In vitro studies have shown an important role for IL-2 in T cell activation and expansion. In vivo, IL-2 is critical for the development, maintenance and function of regulatory T cells (Treg) which provide protection against autoimmune disease. On the other hand, IL-2 can also promote autoimmune inflammation in target organs through its roles in regulating the expression of T cell trafficking genes, and production of Th2 cytokines. Within the CD8+ T cell subset, IL-2 is essential for optimal primary responses and differentiation into terminal effector cells. IL-2 also promotes the development of activated CD8+ T cells into memory cells. (1).

Used mice treated with human IL-2 product to test the IL-2 clearance in the blood.
Were able to use our own IL-2 construct to make a trustable standard curve and comparable with the kit's products.

We use this kit daily.
