Molecular Probes™ TransFluoSpheres™ Carboxylate-Modified Microspheres, 0.04 μm (633/720), 2% solids

Description

• Microspheres (also called latex beads or latex particles) are spherical particles in the colloidal size range that are formed from an amorphous polymer such as polystyrene
• Our Molecular Probes™ TransFluoSpheres™ beads are manufactured using high-quality, ultraclean polystyrene and are loaded with two (or more) fluorescent dyes to produce a microspheres that can be excited by a commonly used excitation source (for example, the 633 nm spectral line of the Red He-Ne laser) but emit at much longer wavelengths, facilitating multicolor experiments and allowing the use of broadband excitation and emission filters
• TransFluoSpheres™ microspheres typically show little or no photobleaching, even when excited with the intense illumination required for fluorescence microscopy
• TransFluoSpheres™ Microsphere Specifications: • Label (Ex/Em): Red-fluorescent (633/720) • Nominal bead diameter: 0.04 μm • Coupling surface: Carboxylate • Solids: 2% Characteristics of the Carboxylate Coupling Surface Carboxylate-modified FluoSpheres™ beads have a high density of pendent carboxylic acids on their surface, making them suitable for covalent coupling of proteins and other amine-containing biomolecules using water-soluble carbodiimide reagents such as EDAC
• Key Applications of Microspheres: • Instrument calibration (flow cytometry, microscopy, HTS, HCS) • Flow testing (microfluidics, blood flow, water flow, and air flow) • Cell biology tracers (cell differentiation and cell tracing) • Immunoassays (agglutination tests, ELISA, particle capture, and contrast reagents) Choices for Fluorescent Microspheres Among our complete offering of fluorescent microspheres products, you’ll find beads with these variations: • Ten fluorescent colors • Ten nominal bead diameters: 0.02μm, 0.04μm, 0.1μm, 0.2μm, 0.5μm, 1.0μm, 2.0μm, 4.0μm, 10.0μm, and 15.0μm • Four surface modifications for protein coupling: carboxylate, sulfate, aldehyde-sulfate, amine • Microspheres that are additionally precoupled with streptavidin, NeutrAvidin, biotin, europium, and platinum Choices for Unstained Microspheres We also offer hundreds of choices for UltraClean™ surfactant-free microspheres for research and commercial applications
