Propidium Iodide Reference Standard - 1 mL

The Propidium Iodide Reference Standard – 1 mL is a high-purity fluorescent DNA intercalating dye widely used as a reference reagent for cell viability, apoptosis, and DNA content analysis in flow cytometry and fluorescence microscopy. Propidium iodide (PI) selectively binds to double-stranded DNA in cells with compromised membranes, enabling clear discrimination between live, apoptotic, and dead cells. This reference standard ensures precise calibration and reproducible fluorescence intensity across instruments, making it ideal for cell cycle analysis, cytotoxicity assays, and cancer research. Supplied as a 1 mL ready-to-use solution, it guarantees consistent performance and stability in flow cytometry, confocal microscopy, and nucleic acid staining protocols. The Propidium Iodide Reference Standard is essential for laboratories conducting cell death assays, DNA quantification, and fluorescence-based diagnostics, providing accurate and reproducible results for reliable experimental outcomes.
