Invitrogen™ NucBlue™ Fixed Cell ReadyProbes™ Reagent by Thermo Fisher Scientific

"I love Nuc Blue. I use it in my research group and in teaching a Tissue Culture course. NucBlue is a nuclear stain and it stains as well if not better than classic nuclear stains. It is so easy to use and very fast to use in an experiment. We joke that NucBlue always works so that it tells you that the experiment worked even if other stains didn't work well. Reproducibility is no problem; NucBlue always works. It is great to hear the oos and ahhs of students doing staining of cells for the first time when they see their NucBlue results! At least one student used the stained cells for a Christmas card and many use the image as a screen saver."
