100bp DNA ladder 100-3000bp

Pre-made and containing loading dye for immediate use, these ready-to-use DNA Markers are specially formulated to run accurately and produce sharp, well defined ladders. Available in six molecular weight ranges and composed of discrete marker fragments isolated from restriction-digested proprietary plasmids, each DNA marker will remain stable for up to 6 months at room temperature, 12 months if kept in the fridge at 4°C or 24 months at -20°C. Cleaver ready to use DNA markers contain high intensity reference bands and may be used to perform size comparisons with DNA molecules ranging from the smallest of PCR fragments to large, linearised cosmid vectors.
