Description

CoraFluor(TM) 1 is a high performance terbium-based TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) or TRF (Time-Resolved Fluorescence) donor for high throughput assay development. CoraFluor(TM) 1 absorbs UV light at approximately 340 nm, and emits at approximately 490 nm, 545 nm, 585 nm and 620 nm. It is compatible with common acceptor dyes that absorb at the emission wavelengths of CoraFluor(TM) 1. CoraFluor(TM) 1 can be used for the development of robust and scalable TR-FRET binding assays such as target engagement, ternary complex, protein-protein interaction and protein quantification assays.

CD160 Antibody [CoraFluor™ 1]

Product Feature: CoraFluor Probes for TR-FRET

CoraFluor™ 1, amine reactive (Catalog:7920) and CoraFluor™ 2, amine reactive (Catalog # 7950) are terbium-based probes that have been developed for use as TR-FRET donors. They emit wavelengths compatible with commonly used fluorescent acceptor dyes such as BODIPY® (or BDY) and Janelia Fluor® dyes, FITC (Catalog # 5440), TMR and Cyanine 5 (Catalog # 5436). CoraFluor™ fluorescence is brighter and more stable in biological media than existing TR-FRET donors, leading to enhanced sensitivity and improved data generation. CoraFluor™ 1 exhibits excitation upon exposure to a 337 nm UV laser.

Background: CD160

CD160, also known as BY55 and NK1, belongs to a class of natural killer (NK) receptors known as the major histocompatibility complex (MCH) class I-dependent NK cell activating receptor (1). CD160 exists as either a glycosylphosphatidylinositol (GPI)-anchored isoform or a transmembrane protein and is expressed on NK cells and cytotoxic T lymphocytes, as well as endothelial cells (1-3). CD160 has both stimulatory and inhibitory receptor functions and regulates cell differentiation and activation (2). The human CD160 protein is 181 amino acids (aa) in length with a theoretical molecular weight (MW) of 19.8 kDa (2,3). However, given that the CD160 protein is subject to glycosylation, addition of disulfide bonds, lipidation, and propitiation, the observed MW is often much higher (2). The human CD160 protein consists of a single immunoglobulin (Ig)-like domain (25-133 aa) and does not contain any immunoreceptor tyrosine-based activation motifs (ITSMs) (2). Thus, CD160 requires the recruitment of adaptor proteins such as phosphoinositide-3 kinase (PI3K) to promote cytotoxic functions including cytokine secretion (1,3).

Identified ligands for CD160 include MHC class I proteins and herpes virus entry mediators (HVEM), each of which has a different effect on NK or T cells (1,3-5). CD160 binds to MHC class I proteins with weaker affinity, but the interaction causes NK cell cytotoxic function and cytokine production (1,3). CD160 engagement of MHC class I proteins and/or HVEM within NK cells promotes ERK1/2 and AKT activation and production of interferon gamma (IFNgamma) (5). Conversely, CD160 binding of HVEM in CD4+ T cells induces inhibitory signaling, signifying both a stimulatory and inhibitory role for CD160 as well as cell-specific context (4,5). Additionally, CD160 plays a role in diseases including certain types of cancer, such as thyroid cancer and colon cancer, viral infections, and autoimmune diseases (3,5). CD160 expression levels on CD8+ T cells have been shown to be elevated in chronic viral infections such as human immunodeficiency virus (HIV) and Epstein Barr virus (EBV) (3). In addition, when CD160 is co-expressed with the programmed cell death protein 1 (PD-1) receptor, T cell exhaustion occurs due to persistent stimulation, leading to inhibited immune response and ability to combat infection (3). CD160 may be a promising therapeutic target in cancer as murine studies have demonstrated that blocking the CD160-HVEM pathway causes a regression of neoplastic tumors in a thyroid cancer model (3-5).
