ReadiDrop™ Propidium Iodide

Use ReadiDrop propidium iodide, a ready-to-use cell viability dye, for excluding dead cells in flow cytometry experiments. As a cell-impermeable assay, ReadiDrop propidium iodide enters a compromised cell and binds to double-stranded DNA/RNA by intercalating between base pairs.

Key Benefits of ReadiDrop Propidium Iodide Cell Viability Assay

• Ideal for cell sorting — fluorescent molecules are suspended in PBS without preservatives
• Stable at room temperature — keep a bottle of ReadiDrop propidium iodide cell viability assay by your cell sorter or cell analyzer for easy access
• No more weighing, pipetting, or diluting — ready-to-use solution to gives 1 µg/ml as the final concentration
