TOOLS DNA view is an innovated nucleic acid stain to replace highly toxic ethidium bromide (EtBr) for detecting nucleic acid agarose gels. It emits green fluorescence when bound to DNA and RNA. TOOLS DNA view is as sensitive as EtBr and the staining protocol is also very similar, however, compared to EtBr, which is known as a strong mutagen, TOOLS DNA view causes much fewer mutations in the Ames test. In addition, it has a negative result in mouse marrow chromophilous erythrocyte micronucleus test and mouse spermary spermatocyte chromosomal aberration test. Most importantly, it is not considered hazardous waste, can be disposed of according to standard laboratories procedures, and is stable for years.
