Rab4 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, Mu, Rt
• Applications: WB, ICC/IF, IHC
• Clonality: Polyclonal
• Host: Rabbit
• Conjugate: CoraFluor 1

Rab4 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

Rab4 is a small GTPase that regulates recycling of proteins, such as GPCRs, from the early endosomes to the cell surface. Overexpression of Rab4 causes a redistribution of receptors on plasma membrane versus endocytic compartments. Rab4 is also involved in the translocation of glucose transporter (Glu4) in adipocytes in response to insulin. Association of Rab4 with transferrin receptor containing early endosomes is mediated through the geranylgeranyl groups at its carboxyl terminus. Rab4 can be used as a marker for early endosomes (see Daro et al. 1996 and Zuk et al. 1999 for more information). Membrane association is also cell cycle dependent, as phosphorylation at its C-terminal cdc2 kinase consensus sequence in mitotic cells leads to dissociation of Rab4 into the cytosol.
