Pi staining emission

Propidium iodide (or PI) is a fluorescent intercalating agent that can be used to stain cells and nucleic acids. PI binds to DNA by intercalating between the bases with little or no sequence preference. When in an aqueous solution, PI has a fluorescent excitation maximum of 493 nm (blue-green), and an emission maximum of 636 nm (red). After binding DNA, the quantum yield of PI is enhan… WebThe ReadiDrop propidium iodide cell viability assay has a number of key benefits and these include: Ideal for Flow Cytometry and Cell Corting - PI is in a PBS solution without preservative. Easy storage: as it is stable at room temperature you can keep a bottle of ReadiDrop propidium iodide cell viability assay by your cell sorter or cell ...
