Fournisseur: SIGMA ALDRICH MICROSCOPY
Description: Fura 2-AM (Fura 2) is a calcium-specific ratio-metric fluorescent dye. It is also known as acetoxy-methyl-ester. In response to calcium ions, ratio metric dyes like Fura 2 changes their respective excitation or emission spectra. The intracellular calcium concentration is determined by the fluorescence emission ratio or excitation at distinct wavelengths. Fura 2 has an emission peak at 505 nm, and the excitation peak ranges between 340 to 380 nm and is the preferred calcium indicator.

Fournisseur: Biotium
Description: Wheat germ agglutinin binds specifically to N-acetylglucosamine in the peptidoglycan layer of gram-positive bacteria. The Live Bacterial Gram Stain Kit contains wheat germ agglutinin (WGA) conjugated to CF™594 to stain the surface of gram-positive cells with red fluorescence. The kit also includes DAPI to stain the DNA of all bacteria with blue fluorescence. Gram-positive bacteria stained using this kit will show a fluorescent blue interior and fluorescent red cell surface, while gram-negative bacterial will be stained with blue fluorescence only.

Numéro de catalogue: (80017.)
Fournisseur: Biotium
Description: This fluorescent biotin derivative is a useful tracer for studying neuronal morphology. The biotin portion of the molecule allows researchers to amplify the fluorescent signal using standard biotin-avidin or biotin-streptavidin biochemistry. The staining can tolerate aldehyde fixation, sectioning, and washing with detergent.
UOM: 1 * 10 mg


Numéro de catalogue: (27088-10MG-F)
Fournisseur: Merck
Description: Chromoionophore III (ETH 5350) is a pH sensitive dye, and is ratiometric that is the fluorescence spectrum has two peaks, and the ratio between these peaks changes according to the changing pH levels.
UOM: 1 * 10 mg


Numéro de catalogue: (90040.)
Fournisseur: Biotium
Description: 5-(and-6)-Carboxy-2′,7′-dichlorofluorescein diacetate, succinimidyl ester is a useful fluorescent tracer that can passively diffuse into cells and covalently label intracellular proteins, resulting in long-term cell labeling. The reagent itself is colorless and nonfluorescent but becomes brightly green fluorescent once it is hydrolyzed by intracellular esterases.
UOM: 1 * 25 mg


Fournisseur: Biotium
Description: MTS, TS and maleimide, and other thiol-modifying reagents and reactive fluorescent dyes.

Fournisseur: SIGMA ALDRICH MICROSCOPY
Description: In living mice, acriflavine hydrochloride has been used in the confocal laser endomicroscopy to check the crypt structure in mucosa. It has also been used in Neurospora strain selection by checking the acriflavine resistance.

Fournisseur: Cayman Chemical
Description: CCVJ is a fluorescent molecular rotor characterised by low background fluorescence, low fluorescence anisotropy, and good water solubility. Fluorescent molecular rotors are molecules whose fluorescence is inversely proportional to its intramolecular rotation.

Fournisseur: SIGMA ALDRICH MICROSCOPY
Description: Rhodamine 123 is useful as a laser dye and to have selective cell growth effects. It has also been used to measure mitochondrial membrane potential.

Numéro de catalogue: (ENZOENZ52152)
Fournisseur: ENZO LIFE SCIENCES
Description: Zinc dye
UOM: 1 * 5 mg


Numéro de catalogue: (59006.)
Fournisseur: Biotium
Description: Similar to A-23187, 4-Bromo A-23187 is used for in situ calibrations of fluorescent Ca2 indicators to equilibrate intracellular and extracellular calcium concentrations and to allow Mn2 to enter cells to quench indicator fluorescence. However, since 4-bromo A-23187 is nonfluorescent, it is preferred over the blue fluorescent A-23187 for calibrations of UV-excited Ca2 indicators such as Indo-1 and Fura-2 in order to keep background fluorescence to a minimum.
UOM: 1 * 1 mg


Numéro de catalogue: (50022.)
Fournisseur: Biotium
Description: Membrane-impermeant calcium indicator that can be loaded into cells via microinjection or scrape loading.
UOM: 1 * 1 mg


Fournisseur: Biotium
Description: Fura-2, AM ester is a ratiometric fluorescent dye that binds to free intracellular calcium, and is the preferred dye for ratiometric imaging microscopy. Fura-2, AM ester is membrane-permeant and thus can be loaded into cells via incubation.

Fournisseur: TCI
Description: 4-Chloro-7-chlorosulphonyl-2,1,3-benzoxadiazole ≥97.0% (par analyse titrimétrique) réactif fluorescent bifonctionnel

Numéro de catalogue: (ENZOENZ42541)
Fournisseur: ENZO LIFE SCIENCES
Description: Enzo cyanine 3 NHS-ester is a reactive, water-soluble fluorescent dye that provides bright orange signal.
UOM: 1 * 50 Nmo


Numéro de catalogue: (ENZOENZ42501)
Fournisseur: ENZO LIFE SCIENCES
Description: Cyanine 3-dUTP can replace TTP in reactions in which it serves as a substrate for E. coli DNA polymerase (holoenzyme and Klenow fragment), T4 and Taq DNA polymerases, reverse transcriptase (from AMV and M-MuLV) and terminal transferase. Fluorescently labeled probes can be prepared with this fluorescent nucleotide by a variety of methods including nick translation, cDNA labeling and 3’-end labeling. Probes generated by these methods are suitable for use for the identification of specific sequences by in situ hybridization procedures on fixed cells and tissues by direct fluorescence detection. Cyanine 3-dUTP can also be used for multicolor fluorescence labeling.
UOM: 1 * 25 Nmo
