Propidium Iodide Solution


Commonly used in flow cytometry experiments for excluding dead cells, the propidium iodide solution enters a compromised cell and binds to double-stranded DNA/RNA by intercalating between base pairs.

Designed for ease of use in cell sorting and flow cytometry applications, the ReadiDrop™ propidium iodide cell viability assay removes the traditional manual weighing, pipetting, and dilution steps: simply add 1 or 2 drops of the propidium iodide solution to assess the health of your cells.

Key Benefits of the 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
