The bands of the marker are prestained with the fluorescent dye SYBR ® Green I, which has been developed specifically for DNA analysis. The dye bounds to the minor groove of DNA and also intercalates into the DNA. It can be excited by UV- and blue light, making it fully compatible with standard UV-transilluminators as well as with modern blue-light illumination (see also ROTIPHORESE ® PROfessional runVIEW, Art. No. 4849.1). When excited, the nucleic acid-bound dye emits a brightly coloured green fluorescence that may be documented by all usual broadband ethidium bromide filters or SYBR ® Green foto filters. 25 kb Fluorescent DNA Ladder 51.6 µg/500 ml, ready-to-use, prestained with Bromophenol blue and Xylene cyanol FF dye The 25 kb fluorescent DNA ladder is a ready-to-use DNA ladder that is premixed with a highly sensitive DNA-binding fluorescent dye and a loading dye for direct gel loading.
