GelStain T is a sensitive, stable, and safe fluorescent nucleic acid dye, offering a higher sensitivity than ethidium bromide (EtBr) without the need for destaining, and designed to stain dsDNA, ssDNA, or RNA in various gels. It boasts non-toxic properties, as it does not penetrate cell membranes and has significantly lower mutagenicity than EtBr. The dye is highly stable, can be used with existing imaging systems, and simplifies the staining process, requiring only a 30-minute post-electrophoresis staining to visualize fragments under a UV-transilluminator.
