SCAP Antibody [CoraFluor™ 1]

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.

• Reactivity: Hu
• Applications: WB, IP

SCAP Antibody [CoraFluor™ 1] Summary

• 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.

Background

Sterol regulatory element binding protein (SREBP) cleavage-activating protein (SCAP) is a molecular chaperone that plays a role in the biosynthesis of cholesterol and triglycerides (1). SCAP is a membrane protein that helps shuttle SREBP from the endoplasmic reticulum (ER) via coat protein II (COPII) vesicles to the golgi where SREBP is cleaved via protease S1P and S2P, becomes activated, and is translocated to the nucleus for transcription (1-3). The SCAP protein has a theoretical molecular weight of 140 kDa and is comprised of 1276 amino acids with an N-terminal domain containing 8 transmembrane alpha helices, where transmembrane 2-6 consist of a sterol-sensing domain, and a C-terminal domain with WD40 motif repeats (1,3). The SCAP-SREBP association plays a pivotal role in regulating lipid metabolism and lipogenesis (1,4). SREBP activation via SCAP is associated with accumulation of triglycerides and cholesterol leading to metabolic disorders including diabetes, atherosclerosis, and nonalcoholic fatty liver disease (NAFLD) (1,4). Animal models have revealed that inhibition or blocking of SCAP using antagonists may be a potential therapeutic target for hyperlipidemia and hypertriglyceridemia (1,4).
