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.

MKK4/MEK4 [p Ser257, p Thr261, p Tyr261] 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: MKK4

MKK4, also known as JNKK1 and SEK1, is a dual specificity kinase that belongs to the Ser/Thr protein kinase family. MKK4 is a direct activator of MAP kinases in response to various environmental stresses or mitogenic stimuli. MKK4 phosphorylates and activates p38 MAP kinase and JNK but not ERK 1/2 (1-2). JNK is activated by dual phosphorylation at Thr and Tyr by MKK4 and MKK7; although MKK4 will preferentially phosphorylate Tyr (3). MKK4 is also known to be a tumor suppressor, as mutations inactivating the MKK4 gene have been found in 5% of a wide variety of tumor types (4).
