Live-or-Dye™ fixable dead cell stains are cell membrane-impermeant amine-reactive dyes. The dyes enter dead cells that have compromised membrane integrity and covalently label free amines on intracellular proteins (Fig. 3). Live-or-Dye™ labeling is extremely stable, allowing the cells to be fixed and permeabilized without loss of fluorescence or dye transfer between cells. The staining protocol has been optimized to maximize live/dead discrimination with minimal live cell staining, in order to prevent interference with immunostaining. Biotium currently offers a wide selection of 14 Live-or-Dye™ stains spanning the fluorescence spectrum for maximal flexibility in designing multi-color flow panels (Fig. 4).

The Best Fixable Dead Cell Stains for Flow Cytometry:

  • Wide selection of dye colors for easy panel design
  • Exceptionally bright dyes for excellent live/dead separation
  • No loss of brightness after fixation
  • For flow cytometry or fluorescence microscopy
  • Dyes designed to fit gaps in spectral flow panels
  • The most options for the 633 nm and 808 nm lasers

New: Live-or-Dye™ Sampler Kits

Live-or-Dye™ stains are available in two sampler kits, each containing five different dye colors, for excitation from all of the popular flow cytometry laser lines (see Live-or-Dye™ Sampler Kits table below). The Live-or-Dye™ Sampler Kit, Standard (32016) was designed for use on the most common flow cytometer laser and filter configurations, with dyes excitable by UV, Violet, Blue, Yellow-Green, and Red lasers. The Live-or-Dye™ Sampler Kit, Spectral (32017) was designed for use in spectral scanning flow cytometry. It contains dyes excitable by UV, Violet, Blue, and Red lasers, all of which have been validated on the Cytek® Aurora spectral cytometer, and chosen for their ability to fill the gaps in many spectral flow panels.

Dead Cell Selective Counterstains

Cyanine-based cell membrane-impermeant nucleic acid stains such as Oxazole Blue (PO-PRO™-1), Oxazole Yellow (YO-PRO®-1), and Thiazole Red (TO-PRO®-3) are dead cell selective stains suitable for flow cytometry. Unlike Live-or-Dye™ Fixable Viability Stains, these cyanine-based dyes are not fixable, but are fluorogenic and highly specific for nucleic acids. This results in bright and sensitive staining that is localized to the nucleus in dead or dying cells. In addition, staining with these dyes can be done directly in cell culture medium without the need for washing. These dyes are generally known by their Thermo Fisher Scientific brand names and are available from blue to far-red. Biotium offers chemically equivalent forms of these dead cell selective stains at a high purity and lower cost.

Cell Proliferation Monitoring by Flow Cytometry

Cell proliferation dyes diffuse passively into live cells and are used for long-term cell labeling. They are initially non-fluorescent esters, but are converted to fluorescent dyes by intracellular esterases and will covalently react with amine groups on intracellular proteins at the same time, forming fluorescent conjugates that are retained in the cell. Immediately after staining, a single bright fluorescent population will be detected by flow cytometry. Each cell division that occurs after labeling is revealed by the appearance of a successively dimmer fluorescent peak on a flow cytometry histogram. Cell proliferation dyes can be used to track cell divisions in vivo or in vitro. The staining can withstand fixation and permeabilization for subsequent immunostaining.

ViaFluor® SE Cell Proliferation Kits

CFSE (also known as CFDA-SE or carboxyfluorescein diacetate, succinimidyl ester) has been used for many years to monitor cell proliferation by flow cytometry. While several alternatives have been developed in more recent years, CFSE remains popular and widely used. Biotium continues to offer CFSE under the tradename ViaFluor® CFSE. However, CFSE has several drawbacks including leakage from the cell, cell toxicity, and bleed-through into the PE and PE-TexasRed® channels.

ViaFluor® 405 SE and ViaFluor® 488 SE cell proliferation dyes were developed at Biotium to provide superior cell staining, fixability, and low toxicity. ViaFluor® 405 is excited with the violet laser and detected in the Pacific Blue® channel, and gives great peaks with no toxicity. It behaves identically to the popular proliferation dye CellTrace™ Violet. ViaFluor® 488 and ViaFluor® CFSE are both detected in the FITC channel, but ViaFluor® 488 was developed as a less toxic, less leaky and more fixable alternative to the classic dye CFSE (Fig. 6). It also has less bleed-through into other channels such as PE and PE-Texas-Red®.

Figure 6. Human PBMCs were stained with ViaFluor® 405 (left), ViaFluor® 488 (center), or ViaFluor® CFSE (right). Cells were stimulated with Dynabeads® Human T-Activator CD3/CD28 beads and 100 ng/mL IL-2. Cells were analyzed 4 days post-induction. CD3+ T-cells are shown. Unstimulated cells (dark peaks) and unstained cells (gray) are shown for comparison.

RedDot™1 Far-Red Nuclear Stain

RedDot™1 is a novel far-red nuclear stain developed at Biotium. RedDot™1
is a live cell stain similar to DRAQ®5 that can be used for cell cycle
distribution analysis (Fig. 7). In addition, RedDot™1 cell cycle analysis does
not require an RNase step unlike the classic nuclear stain Propidium Iodide
(PI). RedDot™1 can also be used as a far-red nuclear counterstain for live
cells in microscopy.

  • Far-red cell membrane-permeant nuclear dye similar to Draq5™.
  • Can be used for DNA content analysis by flow cytometry like Vybrant™ DyeCycle™ Ruby
  • Highly thermostable and photostable, for convenient handling

NucView® Caspase-3 Substrates for Live Cell Apoptosis Monitoring

NucView® caspase-3 substrates are novel fluorogenic substrates developed by Biotium to detect apoptosis in intact cells in real-time. Biotium has invented a new concept in the design of fluorogenic enzyme substrates. The enzyme substrate is attached to a fluorogenic DNA dye. Before cleavage, the dye is non-fluorescent and unable to bind to DNA. Upon enzymatic cleavage of the substrate, the dye is released and becomes capable of binding to DNA to emit fluorescence. In the case of NucView® caspase-3 substrates, the caspase-3/7 substrate peptide DEVD is attached to a DNA-binding dye. The substrate enters the cell cytoplasm where it is cleaved by caspase-3 in apoptotic cells to release the fluorogenic DNA dye, which stains the nucleus (Fig. 10). NucView® can be fixed with formaldehyde after staining, but it cannot be used to stain fixed cells or tissues.

NucView® Advantages

  • Simple, homogeneous assay for endpoint assay or real-time detection in live cells
  • Non-toxic, allowing for multi-day experiments
  • Detect caspase-3 activity and visualize apoptotic nuclear morphology
  • For flow cytometry, fluorescence microscopy, or live cell imaging systems
  • Available as stand-alone substrates or in kits with other apoptosis or necrosis probes
  • Available with blue, green, or red fluorescence
  • NucView® 488 validated in more than 100 cell types and 200 publications – See the list
Figure 10. Principle of NucView® substrate technology. The substrate is non-fluorescent and does not bind DNA. After enzyme cleavage, the high-affinity DNA dye is released to bind DNA and become fluorescent.
Figure 11. Jurkat cells were treated with DMSO (negative control, blue) or 0.1 uM, 0.25 uM, or 1 uM staurosporine (red) to induce apoptosis in the presence of NucView® 530 and CF®405M Annexin V for four hours at 37°C before analysis on a BD LSR II flow cytometer. Staining with NucView® 530 and CF®405M Annexin V increase with increasing concentration of staurosporine.

Mitochondrial Membrane Potential

Loss of mitochondrial membrane potential is a hallmark for apoptosis. Biotium offers MitoView™ 633 dye for membrane potential-sensitive staining of mitochondria by microscopy or flow cytometry. For simultaneous detection of mitochondrial membrane potential and caspase-3 activity, see the NucView®488 and MitoView™633 Apoptosis Assay (Fig. 13).

We also offer MitoView™ 405, which changes localization upon mitochondrial depolarization, and MitoView™ Green, a membrane-potential independent mitochondrial dye that can be used to image mitochondria following mitochondrial depolarization, or after fixation.

In healthy cells, JC-1 dye aggregates in mitochondria as a function of membrane potential, resulting in red fluorescence with brightness proportional to the membrane potential. Conversely, in apoptotic and necrotic cells with diminished mitochondrial membrane potential, JC-1 exists in a green fluorescent monomeric form in the cytosol, allowing of cell viability to be assessed by measuring the ratio of red to green fluorescence by flow cytometry or fluorescence microplate reader. Rhodamine 123 is a green fluorescent mitochondrial membrane potential dye. Red fluorescent TMRM and TMRE are the preferred dyes for quantitative membrane potential measurements.

Apoptosis/Necrosis Kits & Annexin V

Annexin V is a 36 kDa protein that has high affinity for phosphatidylserine (PS). During apoptosis, PS is translocated from the inner to the outer leaflet of the plasma membrane, where it can be stained by fluorescent conjugates of Annexin V. Annexin V conjugates are available with a wide selection of CF® Dyes and other labels, including Near-IR CF® Dye Annexin V conjugates.

We offer many different staining kits with various combinations of dyes, including: NucView® caspase-3 substrate, our bright and photostable CF®488A Annexin V, a variety of dead cell nucleic acid stains, including propidium iodide (PI), 7-AAD, Ethidium Homodimer III (EthDIII), and RedDot™2. See the table below for more details on the various combination kits.

We offer dead cell nucleic acid stains separately as well, including far-red fluorescent RedDot™2 far-red dye and green fluorescent NucSpot® 470 stain.
