Biotium DI-8-ANEPPS

ANEPPS dyes are fast responding membrane potential dyes. Both Di-4-ANEPPS and Di-8-ANEPPS are available. Di-4-ANEPPS has the problem of being internalized in cells over long-term, so it is mainly used for short-term experiments. However, because Di-8-ANEPPS is more lipophilic, the dye is better retained in the outer leaflet of cell plasma membranes and thus more suitable for long-term membrane potential studies. Di-8-ANEPPS is also more photostable and less phototoxic than Di-4-ANEPPS. Properties: Ex/Em (MeOH) = 498/713 nm; Orange red solid soluble in DMF, ethanol or DMSO; Store at 4°C and Protect from light, especially when in solution; C36H52N2O3S; MW:593; [157134-53-7]

Biotium BactoView™ Live Green

BactoView™ Live dyes are fluorogenic live cell bacterial stains. The stains are bright and cell-permeable, they are able to stain both gram-positive and gram-negative bacteria. Stained cells can be detected by fluorescence microscopy or flow cytometry. BactoView™ Live dyes can stain both live and dead bacteria, though dead cells tend to stain a bit brighter than live cells. BactoView™ Live Green can be detected in the FITC channel for flow cytometry and microscopy. Properties: Liquid; Ex/Em= 500/520 nm; Store at 4°C and protect from light.

Biotium ViaFluor CFSE Cell Proliferation Kit

ViaFluor SE Cell Proliferation Kits use non-toxic, amine-reactive dyes to covalently label cells throughout the cell cytoplasm and intracellular compartments. Cell proliferation dyes are commonly used to monitor cell division by flow cytometry. The dyes also can be used to stably label cells to image cell morphology, or to track cell populations in mixed co-culture experiments. Labeling is covalent, so it withstands fixation and permeabilization for subsequent immunostaining. This kit contains ViaFluor CFSE which has an excitation/emission of 495/519 nm. The kit contains 10 lyophilized dye vials. Each vial is sufficient for 18 uL of 5000X stock solution.

Biotium NucSpot Live 650, 1000X in DMSO

NucSpot Live Cell Nuclear Stains are cell-membrane permeable DNA dyes that specifically stain nuclei in live or fixed cells. They have excellent specificity for DNA without the need for a wash step, and they have low toxicity for live cell imaging. The dyes are supplied as 1000X stock solutions in DMSO, and are supplied with a vial of verapamil, which may increase probe retention and staining in some cell types. NucSpot Live 650 stains nuclei with far-red fluorescence and has an excitation/emission of 650/675 nm for detection in the Cy5 channel. Properties: Ex/Em= 650/675 nm; Store at 4°C and protect from light.

Biotium DAPI

DAPI (4′,6-Diamidino-2-Phenylindole, dihydrochloride) is a popular blue DNA dye that is used as a nuclear counterstain in fluorescence microscopy, chromosome staining and flow cytometry. The dye binds to the minor groove of dsDNA with approximately 20-fold fluorescence enhancement, with higher affinity for A-T rich regions. DAPI may be used in fixed cells or in live cells at higher concentrations. The dye has an excitation/emission of 358/461 nm. Properties: Yellow solid soluble in water; Store dessicated at 4°C, protect from light; Ex/Em= 358/461 nm (with DNA); C16H17Cl2N5; MW:350.25; [28718-90-3].

Sigma Aldrich Fine Chemicals Biosciences BioTracker 488 Green Lipid

Lipids are fundamental building blocks of cells and play important cellular roles. Lipids are key components of the plasma membrane and other cellular compartments including the nuclear membrane endoplasmic reticulum Golgi apparatus and trafficking vesicles such as endosomes and lysosomes. Intracellular lipid droplets are cytoplasmic organelles involved in the storage and regulation of triglycerides and cholesterol esters. Lipids have been implicated in various diseases including heart vascular and neurological diseases.BioTracker Lipid dyes rapidly stain lipid droplets in live or fixed cells with no wash step and minimal background staining of cellular membranes or other organelles. Cells also can be fixed and permeabilized after staining.The BioTracker 488 Green Lipid Dye has an excitation around 430 nm and can be excited equally well at 405 nm or 488 nm. In cells it stains lipid droplets with bright green fluorescence using the fITC detection channel.Spectral PropertiesAbsorb

Sigma Aldrich Fine Chemicals Biosciences BioTracker 405 Blue Mitoch

Mitochondria are organelles found in large numbers in most cells in which the biochemical processes of respiration and energy production occurs. In metabolically active cells mitochondria produce a membrane potential by maintaining a proton gradient across the inner and outer membranes. Loss of mitochondrial membrane potential is a hallmark for apoptosis and poor cell health.BioTracker Mitochondria dyes are fluorogenic stains for staining mitochondria in live cells. The dyes are membrane permeable and become brightly fluorescent upon accumulation in the mitochondrial membrane. Staining is lost when mitochondria become depolarized during cell death allowing monitoring of cell viability. The BioTracker 405 Blue Mitochondria Dye can be detected using the blue DAPI channel.Spectral PropertiesAbsorbance 398nmEmission 440nm

Biotium Neuro-DiO

Neuro-DiO was developed as an improved alternative and replacement for the green fluorescent DiO, which has been found to be difficult to use for neurons and cell suspension due to low solubility, tendency to form aggregates and slow lateral diffusion rate. Neuro-DiO and DiO have nearly identical absorption and emission spectra, but the former has better solubility in membranes and does not form nonfluorescent aggregates, which also tend to slow down the dye diffusion rate in membranes. Also offered as ready-to-use CellBrite™ Cytoplasmic Membrane Dyes. Properties: Ex/Em = 484/501nm; Yellow-orange solid soluble in ethanol, hexane, DMSO or vegetable oil; Store at 4°C, protect from light; C67H105ClN2O5S; MW: 1086
