To determine RNA content, pyronin Y was excited at 488 nm and emission was measured at 562–588 nm. DNA content was determined by Hoechst 33342.
WebPyronin Y is a cationic dye that intercalates RNA and is visible as a red band during electrophoresis. It has also been shown to accumulate in mitochondria of viable cells. In conjuction with Methyl Green or Nancy-520, Pyronin Y can be used as a fluorescent differential stain of nucleic acids in paraffin tissue sections. Soluble in water. WebThis chapter describes a protocol for double staining of live cells with Hoechst 33342 and Pyronin Y. Combined with immunophenotyping of intact and live cells Hoechst 33342 and Pyronin Y staining is a powerful noninvasive method for the analysis and isolation of quiescent cells from any defined cell population. less
WebThe methyl green-specific reactivity is attributed to the spatial alignment of the NH 2 groups of the dye to phosphate radicals on the DNA double helix. Pyronin staining, on the other hand, does not show this spatial affinity and any negatively charged tissue constituent will stain red. In practice, not only RNA stains: acid mucins present in ... WebHoechst 33342/Pyronin Y double staining were performed as described previously [8]. Three-dimensional (3-D) culture The 3D culture was performed using the hanging drop technique [23]. Briefly, three hundred of the indicated cells were hung on the lid of a 100 mm dish for 7 days until the 3D spheroids were formed.
