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 monitor cell 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 green fluorescence upon binding to membrane PS. Necrosis has been characterized as passive, accidental cell death resulting from environmental perturbations with uncontrolled release of inflammatory cellular contents. Loss of plasma membrane integrity, as demonstrated by the ability of a membrane-impermeable 7-AAD (Ex/Em = 546/647 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 detect cell apoptosis (green), necrosis (green and/or red) and healthy cells (blue) with a flow cytometer and 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™ Green:
- 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™ Green (Component A) into the cells.
- Optional 1: Add 1 µL of 200X 7-AAD (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 emission filter 530/30 nm (FITC channel- for apoptotic cells), 450/40 nm (Pacific Blue channel- for healthy cells) and 670/14 nm (PE-Cy5 channel- for necrotic cells).
Analyze cells using a flow cytometer:
- Quantify Apopxin™ Green binding using a flow cytometer with emission filter 530/30 nm (FITC channel- for apoptotic cells), 450/40 nm (Pacific Blue channel- for healthy cells) and 670/14 nm (PE-Cy5 channel- for necrotic cells). 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™ Green, 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™ Green and visualized under a microscope.
- Analyze the apoptotic cells with Apopxin™ Green under a fluorescence microscope using the FITC filter. Measure the cell viability using Texas Red filter when 7-AAD is added, and/or DAPI or Violet filter when CytoCalcein™ Violet 450 is added into the cells. The green staining on the plasma membrane indicates the Apopxin™ Green binding to PS on cell surface.
Images
Figure 1. The fluorescence images showing cells that are live (blue, stained by CytoCalcein™ Violet 450), apoptotic (green, stained by Apopxin™ Green), and necrotic (red, indicated by 7-AAD staining) in Jurkat cells induced by 1µM staurosporine for 3 hours. The fluorescence images of the cells were taken with Olympus fluorescence microscope through the Violet, FITC and Texas Red channel respectively. Individual images taken from each channel from the same cell population were merged as shown above. Left: Non-induced control cells; Right: Triple staining of staurosporine-induced cells.
Figure 2. The detection of binding activity of Apopxin™ Green to phosphatidylserine in Jurkat cells. Jurkat cells were treated without (A. Blue) or with 1 μM staurosporine (A. Red) in a 37 oC, 5% CO2 incubator for 5 hours, and then loaded with Apopxin™ Green for 30 minutes. The fluorescence intensity of Apopxin™ Green was measured with a FACSCalibur (Becton Dickinson, San Jose, CA) flow cytometer using FL1 channel.
