See also: Apoptosis and Necrosis
Our Cell Meter™ assay kits are a set of tools for monitoring cell viability. There are a variety of parameters that can be used. This particular kit is designed to simultaneously monitor apoptotic, necrotic, and healthy cells. Apoptosis is described as an active, programmed process of autonomous cellular dismantling that avoids eliciting inflammation. In apoptosis, phosphatidylserine (PS) is transferred to the outer leaflet of the plasma membrane. As a universal indicator of the initial/intermediate stages of cell apoptosis, the appearance of phosphatidylserine on the cell surface can be detected before morphological changes are observed. The PS sensor used in this kit has red fluorescence upon binding to membrane PS. Necrosis has been characterized as passive, accidental cell death resulting from environmental perturbations with the uncontrolled release of inflammatory cellular contents. Loss of plasma membrane integrity, as demonstrated by the ability of a membrane-impermeable DNA Nuclear Green™ DCS1 (Ex/Em = 490/525 nm) to label the nucleus, represents a straightforward approach to demonstrate late-stage apoptosis and necrosis. In addition, this kit also provides a live cell cytoplasm labeling dye, CytoCalcein™ Violet 450 (Ex/Em = 405/450 nm), for labeling living cell cytoplasm. This kit is optimized to simultaneously detect cell apoptosis (red and/or green), necrosis (green), and healthy cells (blue) with a flow cytometer or fluorescence microscope.

PREPARATION OF STOCK SOLUTION
Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.
1. CytoCalcein™ Violet 450 stock solution (200X):
Add 100 µL of DMSO into the vial of CytoCalcein™ Violet 450 (Component D) to make 200X CytoCalcein™ Violet 450 stock solution. Protect from light.

SAMPLE EXPERIMENTAL PROTOCOL
Prepare and incubate cells with Apopxin™ Deep Red:
- Treat cells with test compounds for a desired period of time (4-6 hours for Jurkat cells treated with staurosporine) to induce apoptosis.
- Centrifuge the cells to get 1-5×105 cells/tube.
- Resuspend cells in 200 µL of Assay Buffer (Component B).
- Add 2 µL of 100X Apopxin™ Deep Red (Component A) into the cells.
- Optional 1: Add 1 µL of 200X Nuclear Green™ DCS1 (Component C) into the cells for necrosis cells.
- Optional 2: Then add 1 µL of 200X CytoCalcein™ Violet 450 stock solution into the cells for healthy cells staining.
- Incubate at room temperature for 30 to 60 minutes, protected from light.
- Add 300 µL of Assay Buffer (Component B) to increase volume before analyzing the cells with a flow cytometer or fluorescence microscope.
- Monitor the fluorescence intensity using a flow cytometer with 660/20 nm (for apotosis-APC channel), 530/30 nm (for necrosis-FITC channel) and 450/40 nm emission filter (for healthy cells-Pacific Blue channel) or fluorescence microscope with DAPI (Healthy cells), FITC (Necrosis cells) and Cy5 filters (Apoptotic cells).
Analyze cells using a flow cytometer:
- Quantify Apopxin™ Deep Red binding using a flow cytometer with 660/20 nm (for apotosis-APC channel), 530/30 nm (for necrosis-FITC channel) and 450/40 nm emission filter (for healthy cells-Pacific Blue channel). Note: The flow cytometric analysis of Apopxin™ binding to adherent cells is not routinely tested since specific membrane damage may occur during cell detachment or harvesting. However, methods for utilizing Annexin V for flow cytometry on adherent cell types have been previously reported by Casiola-Rosen et al. and van Engelend et al.
Analyze cells using a fluorescence microscope:
- Pipette the cell suspension after incubation, rinse 1-2 times with Assay Buffer, and then resuspend the cells with Assay Buffer.
- Add the cells on a glass slide that is covered with a glass cover-slip or a black wall/clear bottom 96-well microplate. Note: For adherent cells, it is recommended to grow the cells directly on a cover-slip (or a black wall/clear bottom 96-well microplate). After incubation with Apopxin™ Deep Red, rinse 1-2 times with assay buffer, and then add assay buffer back to the cover-slip (or a black wall/clear bottom 96-well microplate). Invert cover-slip on a glass slide and visualize the cells. The cells can also be fixed in 2% formaldehyde after the incubation with Apopxin™ Deep Red and visualized under a microscope.
- Analyze the apoptotic cells with Apopxin™ Deep Red under a fluorescence microscope using Cy5 filter. Measure the cell viability using FITC filter when Nuclear Green™ DCS1 is added, and/or Violet filter when CytoCalcein™ Violet 450 is added into the cells. The red staining on the plasma membrane indicates the Apopxin™ Deep Red binding to PS on cell surface.

The fluorescence images showing cells that are live (blue, stained by CytoCalcein™ Violet 450), apoptotic (red, stained by Apopxin™ Deep Red), and necrotic (green, indicated by Nuclear Green™ DCS1 staining) in Jurkat cells induced by 1 μM staurosporine for 3 hours. The fluorescence images of the cells were taken with Olympus fluorescence microscope through the Violet, Cy5 and FITC channel respectively. Individual images taken from each channel from the same cell population were merged as shown above. A: Non-induced control cells; B: Triple staining of staurosporine-induced cells.
