WebThe extraordinary stability of TOTO-1–nucleic acid complexes allows the dye–DNA association to remain stable, even during electrophoresis (); thus, samples can be stained with nanomolar dye concentrations prior to electrophoresis, thereby reducing the hazards inherent in handling large volumes of ethidium bromide staining solutions. WebHistological stains that have an affinity for specific cellular components have been in use since at least the 1770s when John Hill used carmine to study tissues. Stain variety exploded during the 1800s with German dye manufacturers, such as BASF, developing aniline, methylene blue, and eosin.Eosin is still in use today with hematoxylin for H&E …
