DiI is a lipophilic membrane stain that diffuses laterally to stain the entire cell. It is weakly fluorescent until incorporated into membranes. This orange—red-fluorescent dye, which is spectrally similar to tetramethylrhodamine, is often used as a long-term tracer for neuronal and other cells. DiI is also available as a solid (D-282), as a paste (N-22880) or as crystals (D-3911).

The CellMask™ Plasma Membrane Stains allow fast and uniform labeling of the plasma membrane without the cell-type differences exhibited by lectins. These stains may be used as a segmentation tool for HCS (high-content screening), as well as to stain cellular plasma membranes for standard fluorescence microscopy. The stain survives fixation, but not permeabilization, so it is not suitable for experiments that also involve probing internal targets via antibodies.

FxCycle™ PI/RNase Staining Solution is used for flow cyotmetric analysis of DNA content in fixed cells. Propidium iodide (PI), a popular red-fluorescent stain, binds to DNA by intercalating between the bases with little or no sequence preference and with a stoichiometry of one dye per 4–5 base pairs of DNA. PI also binds to RNA, necessitating treatment with RNase to distinguish between RNA and DNA staining. This propidium iodide solution includes DNase-free RNase A and a permeablization reagent. It comes ready to use: simply add the staining solution to fixed cells, incubate, and acquire on a ...

The cell-permeant SYTO 82 orange fluorescent nucleic acid stain exhibits bright, orange fluorescence upon binding to nucleic acids. Because the staining pattern of the SYTO dyes in live cells may vary between cell types, we offer the SYTO Orange Fluorescent Nucleic Acid Stain Sampler Kit (S-11360) to enable researchers to find the most appropriate orange-fluorescent SYTO stain for their system.

HCS CellMask™ Red stain (H32712) replaces the HCS CellMask™ Red cytoplasmic⁄nuclear stain (H32711) as a cell delineation tool for HCS platforms. HCS CellMask™ stains label the entire cell (cytoplasm and nucleus) and provide an accurate backdrop against which the features of interest can be assessed. HCS CellMask™ stains can be applied to cells immediately after fixation or in the last step of multiplexing protocols, and they are compatible with detergent-based cell permeabilization protocols. If only nuclear staining is desired, HCS NuclearMask™ stains can be used for measuring DNA content in ...

Alkaline Phosphatase Live Stain is a stem cell imaging product that allows users to differentially stain pluripotent stem cells (PSCs). The dye is a cell-permeable fluorescent substrate for alkaline phosphatase (AP) that is non-toxic to cells, diffusing out over the course of two hours. The Alkaline Phosphatase Live Stain consists of 50 µL of a 500X fluorescein-based dye in DMSO, sufficient for staining two 24-well plates, four 6 cm dishes or two 10 cm dishes. This Alkaline Phosphatase Live Stain allows you to: • Identify pluripotent stem cells with a strong signal above background • Stain PSC...

The intracellular accumulation of neutral lipids, steatosis, is often triggered by drugs that affect the metabolism of fatty acids and/or neutral lipids. HCS LipidTOX™ Green neutral lipid stain was developed to characterize the potentially toxic effects of compounds on lipid metabolism in mammalian cell lines. The LipidTOX™ neutral lipid stain has an extremely high affinity for neutral lipid droplets and can be detected by fluorescence microscopy or an HCS reader. This probe is compatible with the HCS LipidTOX™ phospholipidosis detection reagents (H34350, H34351). HCS LipidTOX™ neutral lipid s...

The lipophilic probe, FM™ 4-64FX exhibits low fluorescence in water but fluoresces intensely upon binding the outer leaf of the plasma membrane providing discrete plasma membrane staining. The binding is rapid and reversible and "FX" denotes that this analog is fixable with aldehyde-based fixatives. It is also an excellent reagent for identifying actively firing neurons and for investigating the mechanisms of activity-dependent vesicle cycling.

Molecular Probes' proprietary Pro-Q Emerald 300 and Pro-Q Emerald 488 Glycoprotein Stain Kits provide the most advanced technology available for detection of glycoproteins in gels and on blots. Gel staining is rapid and very sensitive. In less than three hours, it is possible to detect as little as 300 pg of glycoprotein per band, depending on the degree of glycosylation, making these stains at least 50-fold more sensitive than standard fuchsin staining.
