ER-Tracker™ Red (BODIPY™ TR Glibenclamide), for live-cell imaging (Invitrogen™)

ER-Tracker™ Red dye is cell-permeant, live-cell stain that is highly selective for the endoplasmic reticulum (ER) that when stained using the protocol provided, the staining pattern is partially retained after fixation with formaldehyde. This stain consists of the green-fluorescent BODIPY® TR dye and glibenclamide. Glibenclamide (glyburide) binds to the sulphonylurea receptors of ATP-sensitive K+ channels which are prominent on ER; the pharmacological activity of glibenclamide could potentially affect ER function. Variable expression of sulphonylurea receptors in some specialized cell types may result in non-ER labeling.

LysoTracker® Blue DND-22 is a blue fluorescent dye that stains acidic compartments in live cells with excitation/emission maxima ~373/422 nm.

Yeast Mitochondrial Stain Sampler Kit (Invitrogen™)

The Yeast Mitochondrial Stain Sampler Kit contains sample quantities of five different cell-permeant probes that have been found to label mitochondria in live yeast.

Each of these probes is sequestered in functioning mitochondria.

ER-Tracker™ Green (BODIPY™ FL Glibenclamide), for live-cell imaging (Invitrogen™)

ER-Tracker™ Green dye is cell-permeant, live-cell stain that is highly selective for the endoplasmic reticulum (ER) that when stained using the protocol provided, the staining pattern is partially retained after fixation with formaldehyde. This stain consists of the green-fluorescent BODIPY® FL dye and glibenclamide. Glibenclamide (glyburide) binds to the sulphonylurea receptors of ATP-sensitive K+ channels which are prominent on ER; the pharmacological activity of glibenclamide could potentially affect ER function. Variable expression of sulphonylurea receptors in some specialized cell types may result in non-ER labeling.

LysoTracker™ Green DND-26 - Special Packaging (Invitrogen™)

LysoTracker® Green DND-26 is a green fluorescent dye that stains acidic compartments in live cells with excitation/emission maxima ~504/511 nm.

Image-iT™ TMRM Reagent (mitochondrial membrane potential indicator) (Invitrogen™)

Healthy mitochondrial membranes maintain a difference in electrical potential between the interior and exterior of the organelle, referred to as a membrane potential. Tetramethylrhodamine, methyl ester (TMRM) is a cell-permeant dye that accumulates in active mitochondria with intact membrane potentials. If the cells are healthy and have functioning mitochondria, the signal will be bright. Upon loss of the mitochondrial membrane potential, TMRM accumulation will cease and the signal will dim or disappear. TMRM signal can be detected with fluorescence microscopy, flow cytometry, cell sorting, high-throughput screening, and high content analysis.

• For live-cell dynamic study of mitochondrial membrane potential (not fixable)
• Detectable with RFP/TRITC filter set (absorbance peak: 548 nm, emission peak: 574 nm)
• Mutiplexable with green, deep red, violet, and blue emission dyes, such as GFP, DAPI, Hoechst, HCS LipidTOX, and LysoTracker Deep Red

LysoTracker™ Yellow HCK-123 - Special Packaging (Invitrogen™)

LysoTracker® Yellow HCK-123 is a yellow fluorescent dye that stains acidic compartments in live cells with excitation/emission maxima ~465/535 nm.

MitoTracker™ Red CMXRos - Special Packaging (Invitrogen™)

MitoTracker Red CMXRos is a red-fluorescent dye that stains mitochondria in live cells and its accumulation is dependent upon membrane potential. The dye is well-retained after aldehyde fixation.

Yeast Vacuole Marker Sampler Kit (Invitrogen™)

The Yeast Vacuole Marker Sampler Kit contains sample quantities of a series of both novel and well established vacuole marker probes for the study of yeast cell biology. There are two blue-fluorescent coumarin-based stains that selectively stain the lumen of the yeast vacuole. There is also a green-fluorescent yeast vacuole membrane marker MDY-64 for staining the vacuole membrane. Finally, this kit also includes the commonly used vaculate marker 5-(and-6)-carboxy-2',7-dicholorofluorescein diacetate (carboxy-DCFDA) as a standard.

LysoTracker™ Red DND-99 - Special Packaging (Invitrogen™)

LysoTracker® Red DND-99 is a red-fluorescent dye for labeling and tracking acidic organelles in live cells.

Features of all LysoTracker® probes include:

 High selectivity for acidic organelles
•  Good retention after aldehyde fixation
•  Effective labeling of live cells at nanomolar concentrations
•  Live cell imaging
•  Excitation/Emission: 577/590 nm

Simple, Highly Specific, One-Step Staining and Tracking of Acidic Organelles
The LysoTracker® probes consist of a fluorophore linked to a weak base that is only partially protonated at neutral pH. This allows LysoTracker® probes to freely permeate cell membranes enabling them to label live cells. LysoTracker® probes are highly selective for acidic organelles, and unlike dinitrophenyl (DNP), LysoTracker® probes do not require use of a second antibody for detection.

LysoTracker® probes are available in a variety of fluorescent colors.
