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.

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: PI 3-Kinase p55 gamma

PI 3-Kinase p55 gamma, also referred to as PI3Kp55 gamma or p55gamma, is a regulatory subunit of phosphatidylinositol 3-kinase (PI 3-Kinase / PI3K) (1). Class 1A PI 3-Kinases are heterodimers consisting of one 110 kDa catalytic subunit (p110 alpha, beta, or delta) and one regulatory subunit (p85 alpha, p85 beta, p55 alpha, p50 alpha, or p55 gamma) (1). The p55 gamma regulatory subunit is encoded by the PIK3R3 gene and is predominantly expressed in the brain (2). Human PI 3 Kinase p55 gamma protein is 461 amino acids (aa) in length with a theoretical molecular weight of ~54 kDa (3). Structurally, PI 3-Kinase p55 gamma contains a proline rich domain (aa 34 - 44) and two Src homology domains (SH2, aa 65 - 160 and 358 - 452) (1,3). In general, Class 1A PI 3-Kinases are activated through the binding of membrane-bound tyrosine kinase receptors, such as insulin-like growth factor 1 (IGF-1) (1,2,4). Activation of PI 3-Kinase results in the phosphorylation of phosphatidyl inositol and a downstream signaling cascade of the AKT/mTOR pathway (2,4). PI 3-Kinase pathway activation results in a number of cellular responses including proliferation, survival, growth, migration, membrane trafficking, and metabolism (2). The PI3-Kinase/AKT/mTOR pathway has been shown to be dysregulated in a number of cancers, largely through loss or inactivation of the tumor suppressor PTEN (4). Furthermore, one study found that anaplastic lymphoma kinase (ALK) promoted cell migration during brain development specifically through the p55 gamma regulatory subunit of PI 3-Kinase (5).
