AlphaLISA Human IL2 Biotin-Free Detection Kit is designed for the quantitative detection of human IL-2 in serum, cell culture medium, and other samples types using a homogeneous (no wash steps, no separation steps) assay. The biotin-free kit uses anti-DIG (anti-Digoxin) Donor beads instead of streptavidin Donor beads, which makes the kit compatible with high-biotin culture media and other sample types that contain high levels biotin (including brain/liver tissue extracts, milk and eggs).
For research use only; not for diagnostic procedures. All products to be used in accordance with applicable laws and regulations including without limitation, consumption & disposal requirements under European REACH regulations (EC 1907/2006).

Features and Benefits:
Interleukin 2 (IL-2), formerly known as T-cell growth factor (TCGF), is a 15 kDa immunoregulatory lymphokine known to be produced by lectin- or antigen-activated T cells and capable of inducing the thymic expansion of recently activated antigen-specific T lymphocytes. However, since T-cell immunity could be elicited to various agents in the absence of IL-2 in vivo, it is currently thought that the main non-redundant activity of this cytokine is the induction of the suppressor function of CD4+CD25+ regulatory T cells (Treg) in peripheral lymph nodes to ensure suppression of autoreactive T cells that escape negative selection. Moreover, recent findings suggest that IL-2-mediated regulation of Treg cells is important in the prevention of type 1 diabetes and autoimmune disease.
AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA biotin-free assay, a DIG-labeled anti-analyte antibody binds to the anti-DIG-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater assay throughput and sensitivity has evolved. In response, more robust immunoassays have been developed to address some of the limitations of the standard, colorimetric ELISA.
Find out about the most common limitations of traditional ELISAs and how different ELISA alternative technologies address these limitations.
Breast cancer tumors can adapt to immune cell infiltration by responding to the increased concentration of interferon gamma (IFN-ɣ) and other cytokines secreted by subsets of T lymphocytes with the upregulation of the immune checkpoint proteins such as Programmed cell death ligand 1 (PD-L1). These checkpoint proteins allow the tumors to evade immune targeting and reduce the immune response, thus promoting tumor progression.
In this application note, you will learn:
Various cytokines are secreted during an active immune response that can have modulatory effects on target cell populations, including interferon gamma (IFN-ɣ), tumor necrosis factor alpha (TNFa) and several interleukins.
