eBioscience™ Phalloidin eFluor™ 570 (Invitrogen™)

Phalloidin is a peptide toxin isolated from the Amanita phalloides mushroom. Phalloidin selectively binds F-actin and functions to stablilize actin polymers by inhibiting the dissociation of actin monomers from the filament ends. Because F-actin polymers compose the cytoskeleton of almost all eukaryotic cells, phalloidin conjugates can be useful probes for visualizing the structure of live or fixed cells using microscopy. Phalloidin eFluor™ 570 can be used to label cells of multiple species.

Phalloidin eFluor™ 570 is supplied as a frozen liquid. To prepare the 1000X stock solution, thaw the vial, add 30 uL high-quality anhydrous DMSO, mix and briefly spin down. The resulting solution (phalloidin DMSO stock) should be aliquoted, protected from light and moisture, and stored at -20°C. To prepare a 1X working solution of phalloidin conjugate, add 1 uL of 1000X phalloidin DMSO stock solution to 1 mL of PBS containing 1% BSA.

Phalloidin is a bicyclic peptide belonging to a family of toxins isolated from the deadly Amanita phalloides ""death cap"" mushroom and commonly used in imaging applications to selectively label F-actin. Fluorescently-labeled phalloidin has several advantages over antibodies for actin labeling, including virtually identical binding properties with actin from different species of plants and animals, and low non-specific binding. Phalloidin binds F-actin with high selectivity, while Alexa Fluor Plus 750 provides violet fluorescence of unparalleled brightness and photostability.

Use in multiple applications
Alexa Fluor 750 Plus Phalloidin can be used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations. Its staining is fully compatible with other fluorescent stains used in cellular analyses, including fluorescent proteins, Qdot nanocrystals, and other Alexa Fluor conjugates including secondary antibodies.

SYTO™ Deep Red Nucleic Acid Stain, for live cells (Invitrogen™)

SYTO Deep Red Nucleic Acid Stain is cell-permeant dye that specifically stains the nuclei of live, dead, or fixed cells. It can be used in live-cell fluorescent imaging workflows and in fixed cell workflows, including immunocytochemistry, immunohistochemistry, and immunofluorescence experiments. After a brief incubation with the stain, the nuclei of live, dead, or fixed cells fluoresce with a deep red/far red signal that is detectable with a Cy5/deep red standard filter set or laser configuration.

• Cell-permeant dye that stains nuclei of live, dead, or fixed cells
• Detectable with deep red/Cy5 fluorecence filter set, with excitation/emission maxima of 652/669 nm
• Five times greater fluorescent signal when staining dsDNA vs RNA

SYTO Deep Red Nucleic Acid Stain can be mulitplexed with blue, green, orange, red, and near-IR fluorophores when compatible fluorescent filter/laser configurations are used. The stain increases in fluorescence with increasing concentrations of dsDNA. SYTO Deep Red Nucleic Acid Stain displays up to five times more fluorescence when incubated with dsDNA vs RNA, unlike DRAQ or other live-cell deep red nucleic acid stains. It has a bright initial signal and excellent photo stability in a typical imaging experiment. These properties make the stain ideal as a simple and quantitative single-step dead/fixed cell nucleus-labeling dye for use with fluorescence microscopes, fluorimeters, fluorescence microplate readers, and flow cytometers. The stain has been successfully used on live monolayer cells and spheroid cells and as a nuclear counter-stain in immunocytochemistry.

SYTOX™ Deep Red Nucleic Acid Stain, for fixed/dead cells (Invitrogen™)

SYTOX Deep Red Nucleic Acid Stain is a high-affinity nucleic acid stain that easily penetrates cells with compromised plasma membranes and yet does not cross the membranes of live cells. With minimal cytoplasmic staining, SYTOX Deep Red stain is particularly useful in immunocytochemistry (ICC), immunohistochemistry (IHC), and immunofluorescence (IF) experiments for staining of nuclei of fixed cells. After a brief incubation with SYTOX Deep Red stain, the nucleic acids of dead or fixed cells fluoresce a bright, deep red/far red and can be detected with a CY5/Deep Red standard filter set or laser configuration.

Features of SYTOX Deep Red Nucleic Acid Stain include:
• Impermeant to live cells; permeant to dead or fixed cells
• Excitation/emission peak: 660/682 nm
• Use with Cy5 traditional filter set or 647 laser line
• Works with mammalian cells in mono layer or 3D cell culture, animal tissue, and bacteria
• Detectable with fluorescence micro¬scopes, fluorimeters, fluorescence microplate readers, and flow cytometers

SYTOX Deep Red Nucleic Acid Stain is multiplexable with blue, green, orange, red, and near IR fluorophores, when compatible fluorescent filter/laser configurations are used. SYTOX Deep Red stain shows increased fluorescence with increasing concentrations of dsDNA, but does not show much affinity for RNA or ssDNA. It has a bright initial signal and excellent photo stability in a typical imaging experiment. These properties make SYTOX Deep Red stain a simple and quantitative single-step dead/fixed cell nucleus-labeling dye for use with fluorescence micro¬scopes, fluorimeters, fluorescence microplate readers, and flow cytometers.

SYTOX Deep Red Nucleic Acid Stain had been used successfully in mono-layer cells, thin-sliced tissue, thick-sliced tissue, 3D cell cultures/spheroids, and bacteria. It is supplied at a 1 mM concentration in DMSO (~2000X concentration). A concentration of 0.5 µM (1X) is recommended for most applications and cell types. In fluorescent imaging of various mammalian cells, a concentration range of 2.5 µM to 0.25 µM has been used. For viability testing by flow cytometry, a concentration of 1 µM to 10 nM has been used for Jurkat cells and a range of 4 µM to 0.5 µM has been used with E. coli.

Bis-ANS (4,4'-Dianilino-1,1'-Binaphthyl-5,5'-Disulfonic Acid, Dipotassium Salt) (Invitrogen™)

Bis-ANS is superior to 1-8-ANS as a probe for nonpolar cavities in proteins, often binding with an affinity that is orders-of-magnitude higher. Anilinonaphthalene sulfonates (ANS) are essentially nonfluorescent in water, only becoming appreciably fluorescent when bound to membranes. This property makes it a sensitive indicator of protein folding, conformational changes and other processes that modify the exposure of the probe to water.
