Propidium Iodide: Precision in Cell Viability and Apoptos...

2025-10-21

Propidium iodide (PI) stands apart as a gold-standard fluorescent DNA stain, empowering researchers to execute robust cell viability assays, apoptosis detection, and cell cycle analysis with unmatched specificity. Its unique membrane impermeability, strong fluorescence, and compatibility with advanced flow cytometry workflows enable quantitative analysis of necrotic and late apoptotic cells, delivering crisp, artifact-free data even in complex immune cell models.
