A cellular grid was generated from the propidium iodide channel of the most median optical section using Merrysim 37. For each cell defined in the grid, ...

Cervical cancers cells showed an increase in the uptake of a dye known as propidium iodide, demonstrating a breach of their cell membranes. More dramatically, ...

Evidence of hippocampal neuronal degeneration in 10 month old animals: irregularly shaped neurons with tau pathology that stained with propidium iodide. As characteristics of apoptosis were not ...
