Staining of a mixture of live and heat killed Jurkat cells with ReadiDrop Propidium Iodide for 1 min prior to analysis

Jurkat cells were fixed in 70% cold ethanol, treated with RNAse and stained with ReadiDrop Propidium Iodide (1351101) to reveal the stages of the cell cycle. Doublets were excluded prior to analysis. Data acquired on the ZE5™ Cell Analyzer.

Jurkat cells were treated as shown with staurosporine at 1μM to induce apoptosis. The cells were then stained with annexin V FITC (ANNEX300F) and ReadiDrop™ propidium iodide (1351101). Apoptotic cells positive for annexin V can be seen in the bottom right quadrant and dead cells positive for both annexin and PI in the top right quadrant. Healthy cells are negative for both stains. Data acquired on the ZE5™ Cell Analyzer.

Jurkat cells were treated as shown with staurosporine at 1μM to induce apoptosis. The cells were then stained with Caspase 3/7 FAM FLICA™ (ICT093) and ReadiDrop™ propidium iodide (1351101). Apoptotic cells positive for caspases can be seen in the bottom right quadrant and dead cells positive for both caspase and PI in the top right quadrant. Healthy cells are negative for both stains. Data acquired on the ZE5™ Cell Analyzer.

Jurkat cells were treated as shown with 6 μM Camptothecin to induce apoptosis. The cells were then stained with SR FLICA Caspase-9 Kit (ICT961) and ReadiDrop™ Propidium Iodide (1351101). Apoptotic cells positive for caspases can be seen in the bottom right quadrant and dead cells positive for both caspase and PI in the top right quadrant. Healthy cells are negative for both stains. Data acquired on the ZE5™ Cell Analyzer.

Jurkat cells were treated as shown with staurosporine at 1 μM to induce apoptosis. The cells were then stained with FAM FLICA Poly Caspase Kit (ICT091) and ReadiDrop™ Propidium Iodide (1351101). Apoptotic cells positive for caspases can be seen in the bottom right quadrant and dead cells positive for both caspase and propidium iodide in the top right quadrant. Healthy cells are negative for both stains. Data acquired on the ZE5™ Cell Analyzer.

Jurkat cells were treated as shown with staurosporine at 1 μM to induce apoptosis. The cells were then stained with AnnexinV: PE Assay Kit (ANNEX200PE) and ReadiDrop™ Propidium Iodide (1351101). Apoptotic cells positive for annexin can be seen in the bottom right quadrant and dead cells positive for both annexin and propidium iodide in the top right quadrant. Healthy cells are negative for both stains. Data acquired on the ZE5™ Cell Analyzer.

Propidium Iodide (PI) is a fluorescent dye that binds to DNA and RNA in a stoichiometric ratio. PI is not membrane permeable and therefore requires the compromised membranes of dead cells to bind to DNA. Upon excitation with an appropriate light source, dead cells exhibit higher fluorescence intensity than live cells, thereby enabling clear discrimination of these populations by flow cytometry. Dead cells can then be excluded from further analysis and also sorted from cell populations of interest. The spectral properties (Excitation 535 nm/Emission 617 nm) enable use in both single color and multi color flow experiments. The convenient dropper bottle format removes the manual weighing, pipetting and dilution steps required by other commonly available PI products.

Applications of READIDROP™ Propidium Iodide

This product has been reported to work in the following applications. This information is derived from testing within our laboratories, peer-reviewed publications or personal communications from the originators. Please refer to references indicated for further information. For general protocol recommendations, please visit the antibody protocols page.
Application Name Verified Min Dilution Max Dilution
Flow Cytometry 1/250 1/500
Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Instructions For Use
Caution: Wear gloves, safety glasses/face protection, and protective clothing to avoid direct contact of ReadiDrop solutions with skin and eyes. Refer to MSDS for more information.

1. Resuspend 1 x 106 cells in 500 μl flow cytometry buffer (1x phosphate buffered saline with 3% BSA). The cell concentration is now 2 x 106/ml.

2. Add one to two drop of ReadiDrop Propidium Iodide to the cell suspension.

3. Vortex briefly.

4. Incubate for 1-10 min at room temperature.

Note: Adding one drop to a 500 μl cell suspension produces a final dye concentration of 1 μg/ml. This is typically sufficient to stain 1 x 106 cells. If one drop is not sufficient for your cell type, adding a second drop may improve staining efficacy. When working with a larger volume of cells, scale ReadiDrop solution amount accordingly.

5. Analyze cells by flow cytometry.

- Detect PI signal in FL3 on Bio-Rad's S3e Cell Sorter. Otherwise, select the most appropriate FL channel on your particular instrument.
