Quanterix Inc TSA Plus TMR 50-150 Slides
TSA Plus tetramethylrhodamine (TMR) detection kit, for amplification of signal in immunohistochemistry (IHC), immunofluorescence (IF) or in situ hybridization protocols. This kit amplifies by depositing extra TMR in the localized area of the probe or antibody.
System Biosciences LLC EXOGLOW MEMBRANE EV LABELING Kit = 25 reactions
Label EV membranes (465 nm excitation/635 nm emission) with a reagent specifically optimized for Exosome labeling. SBI’s new generation of extracellular vesicle (EV) labeling reagents take your EV visualization to new levels of clarity, with low background and high selectivity. Unlike general-purpose labeling reagents that are not optimized for EVs and suffer from high levels of background signal, ExoGlow™-Membrane improves your ability to track and localize EVs by specifically labeling EV membranes with a proprietary fluorescent dye that delivers very low levels of background signal. The result is unmatched EV imaging for more accurate studies (see below for our full range of next generation ExoGlow reagents).
Aat Bioquest iFluor™ 532 succinimidyl ester
AAT Bioquest's iFluor™ dyes are optimized for labeling proteins, in particular, antibodies. These dyes are bright, photostable and have minimal quenching on proteins.
Enzo Life Sciences 5-FITC (ultra pure) (1g). CAS: 3326-32-7
Fluorescein isothiocyanate (FITC) is an amine-reactive fluorescein derivative that yields conjugates with superior stability. Dye synthesis generally results in two isomers that differ slightly in protein binding and may elute differently under chromatographic conditions, complicating analysis in certain situations. The 5-isomer of FITC is the most widely used isoform and has a multitude of applications beyond protein peptide and nucleotide labeling. For example, it is commonly employed as a donor for FRET (Fluorescence Resonance Energy Transfer) based assay systems. An acceptor molecule, such as TRITC, is recommended in such FRET applications. Wavelength Maxima: Excitation 494nm, Emission 520nm Alternative name: 5-Fluorescein Isothiocyanate. Purity: ≥95% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.
Biotium MemBrite™ Fix 594/615 Cell Surface Staining Kit, 100 Reactions
MemBrite™ Fix Cell Surface Staining Kits are designed for covalently staining the surface of live cells to conveniently visualize cell boundaries in immunofluorescence experiments. MemBrite™ Fix are new covalent cell surface stains that react irreversibly with cell surface proteins for staining that can withstand formaldehyde or alcohol fixation, and detergent permeabilization. Unlike lectins such as WGA, which bind specific targets that may vary between cell types, MemBrite™ Fix dyes react widely with cell surface proteins. MemBrite™ Fix staining is rapid and non-toxic to cells, and because MemBrite™ Fix dyes are highly water soluble, they stain cells much more evenly than traditional lipophilic membrane dyes like DiO, DiI, PKH, Vybrant, or CellMask™. This trial size kit has reagents sufficient for 100 labeling reactions. The kit contains 1 vial of MemBrite™ Fix 594/615 that is sufficient for 20 uL of 1000X dye after DMSO reconstitution.
