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 already dead cells are called vital stains (e.g. trypan blue or propidium iodide for eukaryotic cells). Those that enter and stain living cells are...

compromise cell membrane integrity. Vital dyes, such as trypan blue or propidium iodide are normally excluded from the inside of healthy cells; however, if...

stained positively. (Vital stains include dyes like trypan blue and propidium iodide, which are either too bulky or too charged to cross the cell membrane...

membranes are no longer intact. Examples of this type of assay include propidium iodide, trypan blue, and 7-Aminoactinomycin D (7-AAD). Mitochondrial activity...

treated with a fluorescent dye that stains DNA quantitatively, such as propidium iodide (PI) or 4,6-diamidino-2-phenylindole (DAPI). The fluorescence intensity...

detection of zinc increase and the well accepted cell death indicator propidium iodide also occurred in kidney cells. Using the principles of fluorescent...

through intercalation. Examples of such dyes are ethidium bromide and propidium iodide. It is an isomer of acridine. Phenanthridine was discovered by Amé...

Zeta toxin induces reversible protective dormancy and permeation to propidium iodide (PI). This protein family entry consists of several bacterial zeta...
