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

Live cells stained with CellMask Orange Actin Tracking Stain can be fixed, or it can be used with fixed cells. And the stain can be used for multiplexing with antibodies in immunofluorecence (IF), immunocytochemistry (ICC), and immunohistochemistry (IHC) protocols.

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.

CellMask™ Green Plasma Membrane Stain Invitrogen™

The CellMask™ Green Plasma Membrane Stain enables fast and uniform labeling of the plasma membrane in almost all cell types. This stain works rapidly and can be detected using a standard FITC filter set with any imaging instrument. Depending upon the cell type and experimental conditions, the plasma membrane staining will last for 60–90 minutes without detectable internalization, providing enough time for most live cell dynamic studies. The stain survives fixation, but not permeabilization.

Features of the CellMask™ Green Plasma Membrane Stain include:

• Sensitivity—specific and rapid plasma membrane staining
• Excellent retention—staining lasts for 60–90 minutes
• Emission/excitation (522/535 nm) works with standard FITC settings

Drawbacks of Other Methods
The plasma membrane is a convenient marker of cell boundaries and as such, a number of probes have been used for staining of the membrane. Typically, dyes of a lipophilic nature are used; however, they internalize rapidly, offering a very narrow window for imaging. Fluorescently labeled lectins, such as wheat germ agglutinin, have also been employed as plasma membrane stains. Conjugated lectins depend on cell surface sugars for staining and as a result, stain inconsistently with variation across cell types. Robust plasma membrane staining is important for a range of applications including translocation assays, plasma membrane dynamics, and as a general tool for cell identification in traditional and automated imaging and analysis.

How CellMask™ Plasma Membrane Stains Work
CellMask™ Green Plasma Membrane Stain is designed to deliver uniform staining of the plasma membrane across a wide variety of mammalian cell types and is slow to internalize, particularly compared to traditional approaches such as DiI, DiO, and labeled wheat germ agglutinin. CellMask™ plasma membrane stains are amphipathic molecules containing a lipophilic moiety for excellent membrane loading and a negatively charged hydrophilic dye for 'anchoring' of the probe in the plasma membrane. While the CellMask™ plasma membrane stains provide ample opportunity for live cell imaging, the staining pattern is also maintained after fixation with formaldehyde, enabling additional multiparametric imaging options. However, staining with CellMask™ plasma membrane stains does not survive detergent extraction and therefore cannot be used in conjunction with probes that require permeabilization.

ER-Tracker™ Blue-White DPX, for live-cell imaging Invitrogen™

ER-Tracker Blue-White DPX dye is a photostable probe that is selective for the endoplasmic reticulum (ER) in live cells. The cells can be aldehyde-fixed after staining with the dye but significant fluorescence signal will be lost. With excitation at ~374 nm, the environmentally-sensitive probe exhibits emission between 430 and 640 nm. A long-pass DAPI filter works best.
