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.

Propidium iodide (PI) is a popular red-fluorescent nuclear and chromosome counterstain. Since propidium iodide is not permeant to live cells, it is also commonly used to detect dead cells in a population. PI binds to DNA by intercalating between the …

Propidium iodide (PI) binds to DNA by intercalating between the bases with little or no sequence preference and with a stoichiometry of one dye per 4–5 base pairs of DNA.1 PI also binds to RNA, necessitating treatment with nucleases to distinguish between RNA and DNA staining.

Propidium iodide (PI) is a popular red-fluorescent nuclear and chromosome counterstain. Since propidium iodide is not permeant to live cells, it is also commonly used to detect dead cells in a population. PI binds to DNA by intercalating between the …

Propidium Iodide is a nuclear fluorescent stain used for counterstaining paraffin-embedded, formalin-fixed tissue, to discriminate between live vs. dead cells in flow cytometry, and staining metaphase chromosomes or interphase nuclei that have been hybridized with probes detected with Fluorescein, or equivalent fluors.

Feb 7, 2025 · Propidium iodide (PI) staining is a technique used in cell biology for analyzing cell viability, DNA content, and the cell cycle, which are crucial for understanding cellular health and function. PI is a fluorescent molecule that intercalates into double-stranded nucleic acids.

Propidium Iodide is a fluorescent nucleic acid dye which binds only to double-stranded nucleic acids. It has a molecular weight of 668.4, an absorbance maximum of 535nm, and an emission maximum of 617 nm.

Propidium is a quaternary ammonium ion and a member of phenanthridines. It has a role as an intercalator and a fluorochrome.

Propidium iodide is a symmetrical cationic compound that appears as a red or pink powder. Its IUPAC name is 3-ethyl-2-[(3-methyl-1/12-5-oxo-2-thiazolidin-2-ylidene)methyl]thiophenyl]imino]-1,3,4-oxadiazol-2(3H)-one. Its molecular formula is C₁₃H₈I₂N₄, and it …
