Description
The SafeDye 500bp ladder is ideal for determining the size of double-stranded DNA from 500 to 5,000 base pairs. The ladder consists of 10 linear double-stranded fragments. The 2,500bp fragment is present at increased intensity to allow easy identification. All fragments are precisely quantified and mixed during the production.BioLit™ SafeDye emits green fluorescence when bound to dsDNA, ssDNA and RNA. This stain has a fluorescence excitation maxima when bound to nucleic acid at approx. 290-320nm and emits at 490nm. This dye replaces Ethidium Bromide (toxic, potential mutagen) for visualisation of DNA or RNA in Agarose gel
