Thiazole Green, which is structurally identical to SYBR Green I Nucleic Acid Gel Stain, is one of the most sensitive stains available for detecting double-stranded DNA (dsDNA) in agarose, polyacrylamide gels and qPCR. Thiazole Green can also be used to detect single-stranded DNA and RNA in denaturing agarose/formaldehyde and polyacrylamide/urea gels without any prewashing steps, although the sensitivity is lower. Thiazole Green has the identical spectral properties as SYBR Green I (Ex/Em 497/520 nm with DNA). Properties: Orange solution; Ex/Em= 497/520 nm (with DNA); Store at -20°C and protect from light; C32H37ClN4S, MW: 545.19; [163795-75-3].
