| Product Name | Propidium Iodide Staining Solution, 1 mg/mL |
| Catalog No. | RERE-0242 |
| Description | Concentrated propidium iodide stock at 1 mg/mL for laboratories that prefer to control their own working dilution. The dye binds DNA and fluoresces red, and since it cannot cross intact membranes it reports membrane integrity as well as DNA content. Typical applications include flow cytometric cell cycle analysis and apoptosis assays. Store the concentrate at -20 °C away from light; it keeps for 12 months. |
| Intended Use | Preparation of working-strength propidium iodide stain for cell cycle and apoptosis analysis |
| Principle / Technology | Propidium iodide binds DNA and fluoresces red, but only enters cells with compromised membranes |
| Specificity | 1 mg/mL concentrated stock; molecular weight 668.40 for the free dye; 12 month shelf life |
| Reaction Conditions / Protocol | Dilute the stock in the staining buffer to the required working concentration and stain the cells away from light |
