ZicherRed isÊa highly sensitive and environmentally safe fluorescent nucleic acid dyeÊfor detection of DNA and RNA in agarose and polyacrylamide gels. ZicherRed Nucleic Acid Safe Gel Stain emits red fluorescence when bound to dsDNA, ssDNA, and RNA and replaces the need for the mutagenic ethidium bromide, commonly used in gels staining procedures for visualization of nucleic acids. ZicherRed is not cell-permeable and nonmutagenic in the Ames test. DNA visualization after staining with ZicherRed can be done using conventional gel imaging instruments (UV transilluminators).
