Staining with pyronin Y detects changes in conformation of RNA during mitosis and hyperthermia of CHO cells.


Cellular RNA in Chinese hamster ovary (CHO) cells synchronized in mitosis (M) or G2 phase, as well as in interphase cells subjected to hyperthermia (42 degrees C, 10 min), was stained with acridine orange (AO), ethidium bromide (EB), or pyronin Y (PY) and the resultant fluorescence was measured by flow cytometry. Total RNA content detected after staining… (More)
