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(IM) 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.

Background: B7-2/CD86

B7-2, also referred to as CD86, is a glycosylated type 1 membrane protein that is a member of the immunoglobulin (Ig) superfamily (1). B7-2/CD86 is constitutively expressed on antigen presenting cells (APCs) such as dendritic cells (DCs), macrophages, and B cells and functions in controlling immune responses through either costimulatory or coinhibitory signals (1,2). Expression of B7-2 is upregulated by APCs upon activation and can be induced in T cells (1,3). The human B7-2 protein, encoded by the CD86 gene, is 329 amino acids (aa) in length with a theoretical molecular weight (MW) of 37.6 kDa (4). The B7-2 protein contains characteristic Ig variable-like (IgV) and constant-like (IgC) domains within its extracellular region (1,3). B7-2/CD86 has structural similarity and shares ~25% sequence homology with another B7 family molecule, B7-1/CD80 (3,5). Both B7-1 and B7-2 are ligands for the activating receptor CD28 and the regulatory receptor cytotoxic T-lymphocyte antigen 4 (CTLA-4) which are expressed on subsets of T cells (1-3,5-7). However, B7-1 and B7-2 bind to CTLA-4 with higher affinity than CD28 (3,5,6). B7-2/CD86 binding to CD28 results in costimulatory signals to promote T cell activation, proliferation, and cytokine production (1-3. 5-7). Binding to CTLA-4 initiates coinhibitory signaling to attenuate the pro-inflammatory T cell response, while also promoting the suppressive function of regulatory T (Treg) cells through expression of indoleamine 2,3-deoxygenase (IDO) (1-3,6,7). Molecules involved in T cell co-signaling have become considerable targets of interest for cancer immunotherapy (7). The anti-CTLA-4 monoclonal antibody ipilimumab, first approved for the treatment of metastatic melanoma, prevents B7-1/B7-2 molecules from binding to CTLA-4, thus driving B7-CD28 binding and promoting costimulatory signals and antitumor effects (1,7,8). Combination therapies targeting co-signaling molecules are currently under investigation to improve antitumor response for treatment of both melanoma and non-melanoma cancers (7,8).
