Stock Solution (1 mg/ml in water) RNaseA solution (7 mg/ml in 10 mM Tris.HCl pH 7.5, 15 mM NaCl) 120 ml working Staining Solution. Since propidium iodide is not permeant to live cells, it is also commonly used to detect dead cells in a population. All immunohistochemistry-stained sections were subsequently stained with 2.5 μM fluoro-styrylbenzene (FSB; Congo red derivative) (Santa Cruz) in 1× PBS and propidium iodide (Sigma) washed before mounting. However, it can easily penetrate dead or damaged cells and as such is commonly used for identifying cell viability in a population or as a counterstain in multicolor fluorescent techniques. PROPIDIUM IODIDE Sigma Prod. Since propidium iodide is not permeant to live cells, it is also commonly used to detect dead cells in a population. I want to analyze cell cycle (apoptosis specifically) using FACS with propidium iodide staining. 6 ml 20 X P.I. Model # P4170-10MG ... Propidium iodide may be used in flow cytometry to evaluate cell viability when used with other dyes that stain viable cells or cells that are early in the apoptosis process. Early redistribution of plasma membrane phosphatidylserine is a general feature of apoptosis regardless of the initiating stimulus: inhibition by overexpression of Bcl-2 and Abl. PI/RNase is commonly used as a nuclear stain in fluorescent microscopy and as a DNA content determinant in cell cycle analyses by flow cytometry. Reference; An H, Chung K, Park H, Hong J, Gim J, Choi H, et al. In aqueous solution, the dye has excitation/emission maxima of 493 / 636 nm. A liquid formulation in an ultra-convenient dropper bottle (Figure 2) allows you to stain your cells whenever and wherever they are ready. For Microscopy analysis: PI can be viewed using rhodamine(red) filter (λ= 536/617). Propidium iodide and 7-AAD can be used to stain dead cells so that they may be excluded from analysis in standard live cell surface staining protocols.
