Easily perform flow cytometry, microscopy, HTS, HCS, immunoassay, and other laboratory applications using our extensive selection of FluoSpheres Carboxylate-Modified Microspheres. FluoSphere beads can be used in passive adsorption or active, covalent coupling of proteins, nucleic acids, and biomolecules for particle capture applications. FluoSphere microspheres are loaded with proprietary fluorescent dyes, making them the brightest microspheres available.
Visualize the brightest fluorescence for laboratoy applications including fluorescence microscopy, flow cytometry, HTS, HCS, and cell tracing with our Carboxylate-Modified FluoSphere Microspheres, which are manufactured from polystyrene microspheres and loaded with different proprietary dyes. Using specialized staining methods enables all of the fluorescent dye molecules to be contained inside each polystyrene microsphere instead of on the bead's surface. This protective environment within the bead shields the dye from detrimental environmental effects, such as photobleaching. Our carboxylate-modified microspheres are coated with a hydrophilic polymer containing multiple carboxylic acids for covalent attachment of ligands. A range of particle sizes is available for different research uses and experiments.

Frequently asked questions (FAQs)
I read that carboxylate-modified latex (CML) beads have a "fluffy coat" of carboxyl groups on their surface. What is meant by this?
I have some FluoSpheres polystyrene microspheres, with 20 nm diameter. They are aggregating a lot. What can I do about it?
I sonicated my 2.0 µm carboxylate-modified microspheres, as recommended, but saw foaming (bubbles) on top of the solution. Should I be concerned?
How long and at what concentration should I sonicate my FluoSpheres Carboxylate-Modified Microspheres (Cat. No. F8826) before using them?
What is the warranty for FluoSpheres microspheres?

Abstract
Tuftsin binds neuropilin-1 through a sequence similar to that encoded by exon 8 of vascular endothelial growth factor.
Journal:The Journal of biological chemistry
PubMed ID:16371354
Somatic exocytosis of serotonin mediated by L-type calcium channels in cultured leech neurones.
Journal:J Physiol
PubMed ID:12562971
'We studied somatic exocytosis of serotonin and its mediation by L-type calcium (Ca2+) channels in cultured Retzius neurones of the leech. Exocytosis was induced by trains of impulses at different frequencies or by depolarisation with 40 mM potassium (K+), and was quantified by use of the fluorescent dye FM 1-43.
Light transmission technique for the evaluation of colloidal transport and dynamics in porous media.
Journal:Environ Sci Technol
PubMed ID:12953883
Colloidal transport in porous media has been typically studied in column experiments from which data analysis was limited to the evaluation of effluent breakthrough curves and/or destructive sampling at the end of the experiments. The internal processes occur within a "black box", where direct observation is not possible and therefore
Multiple effects on Clostridium perfringens binding, uptake and trafficking to lysosomes by inhibitors of macrophage phagocytosis receptors.
Journal:Microbiology
PubMed ID:12777479
Clostridium perfringens is a Gram-positive, anaerobic bacterium that is the most common cause of gas gangrene (clostridial myonecrosis) in humans. C. perfringens produces a variety of extracellular toxins that are thought to be the major virulence factors of the organism. However, C. perfringens has recently been shown to have the
