RedSafe™ Nucleic Acid Staining Solution (20,000x) is a new and safe nucleic acid staining reagent and an alternative to EtBr (ethidium bromide). When bound to nucleic acids, the RedSafe™ Nucleic Acid Staining Solution exhibits two fluorescence excitation maxima at 309 nm and 419 nm and is visible at a wavelength of 514 nm. Compared with EtBr, a potent carcinogen, RedSafe™ Nucleic Acid Staining Solution showed almost no mutation in the Ames test and negative results in mouse marrow chromophilous erythrocyte micronucleus test and mouse spermary spermatocyte chromosomal aberration test. 


  • Used for detecting double-strand DNA and single-strand RNA
  • Safe alternative to EtBr staining
  • As sensitive as EtBr 
  • Allows visualization of DNA (>50 ng) in agarose gel under visible light
  • Non-toxic, non-mutagenic and non-carcinogenic
