WebDec 2, 2024 · It is as sensitive as EtBr but with lower mutagenicity. Bands of 1-5 ng can be detected. It can also be used for staining RNA in gels. GelRed – GelRed is a sensitive, robust, and safe DNA stain. It is less mutagenic than ethidium bromide, stable in extreme heat and light, and can be visualized using UV light. WebEthidium bromide stains DNA in a concentration-dependent manner such that the more DNA present in a band on the gel, the more intensely it will stain. This relationship makes it possible to estimate the quantity of DNA present in a band through comparison with another band of known DNA amount. If the intensities of two bands are similar, then ...
