Our Cell Meter™ assay kits are a set of tools for monitoring cell viability. There are a variety of parameters that can be used for monitoring cell viability. This particular kit is designed to monitor cell apoptosis through measuring the translocation of phosphatidylserine (PS). In apoptosis, PS is transferred to the outer leaflet of the plasma membrane. The appearance of phosphatidylserine on the cell surface is a universal indicator of the initial/intermediate stages of cell apoptosis and can be detected before morphological changes can be observed. This kit uses a fluorescent Annexin V that specifically binds PS. Annexin V conjugates have been demonstrated to selectively bind PS. This particular assay kit is optimized to monitor cell apoptosis using a flow cytometer with the FITC channel (green fluorescence).

Components

Example protocol

AT A GLANCE

Protocol Summary

Prepare cells with test compounds (200 µL/sample).
Add Annexin V-iFluor® 488 stock solution.
Incubate at room temperature for 30 - 60 minutes.
Analyze cells using a flow cytometer with a 530/30 nm filter (FITC channel).

Important

Before starting the experiment, thaw the vial of 100X Propidium Iodide (Component C) at room temperature.

SAMPLE EXPERIMENTAL PROTOCOL

Treat cells with test compounds for a desired period of time (4 - 6 hours for Jurkat cells treated with camptothecin) to induce apoptosis.

Note: Annexin V flow cytometric analysis on 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.
Centrifuge the cells to get 1 - 5 × 10⁵ cells/tube.
Resuspend cells in 200 µL of Assay Buffer (Component B).
Add 2 µL of Annexin V-iFluor® 488 (Component A) into the cells.
Optional: Add 2 µL of 100X Propidium Iodide (Component C) for necrosis cells.
Incubate at room temperature for 30 to 60 minutes, protected from light.
Optional: Add 200 to 300 µL of Assay Buffer (Component B) to increase volume before analyzing the cells with a flow cytometer.
Monitor the fluorescence intensity of Annexin V-iFluor® 488 using a flow cytometer with a 530/30 nm filter (FITC channel). Measure the cell viability using the 610/20 nm filter (PE-Texas Red channel) after adding propidium iodide to the cells.

Figure 1. The detection of binding activity of Annexin V-iFluor® 488 and phosphatidylserine in Jurkat cells. Jurkat cells were treated without (Blue) or with 20 µM camptothecin (Red) in a 37 °C, 5% CO2 incubator for 4-5 hours, and then dye loaded with Annexin V-iFluor® 488 for 30 minutes. The fluorescence intensity of Annexin V-iFluor® 488 was measured with a FACSCalibur (Becton Dickinson) flow cytometer using the FL1 channel.

Figure 2. Effect of FSS on apoptosis and necrosis in tubular cells. Confluent monolayers of HK-2 cells were submitted to FSS 0 (static) or FSS 0.5 Pa (FSS 0.5) for 48h. A/ Cells were stained with Annexin-V and then immediately subjected to analysis of phosphatidylserine externalization (Annexin-V fluorescence, X-axis) and Propidium Iodure (PI) uptake (PI fluorescence, Y-axis) using flow cytometry. Living, early apoptotic or necrotic (primary or secondary) cells were distinguished by the criteria of Annexin-V−/PI−(bottom left quadrant), Annexin-V+/PI− (bottom right quadrant) and Annexin-V+/PI+ (upper right quadrant), respectively. B/ Proportions of early apoptosis and necrosis cells were quantified and results are expressed as a percentage of the total population of cells. Data represent mean ± SEM of 7 experiments. *HK-2 cells were assessed for apoptosis and necrosis using Cell Meter Annexin V Binding Apoptosis Assay Kit (AAT Bioquest), according to the manufacturer's instructions.
