SuperStain is a biological macromolecule that cannot penetrate cell membranes into
cells. Compared to the strong mutagenicity of EB,
it is a safe and non-toxic nucleic acid dye. Since SuperStain and EB have the same
spectral characteristics, the observation device can detect the DNA band under normal
ultraviolet light without changing the filter. It has the advantages of non-toxicity, high
sensitivity and high stability.
