Description
The SM-DM2100 ExcelBand 100 bp DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct loading on gel. The SM-DM2100 DNA marker is composed of 11 individual DNA fragments: 1.5k, 1k, 900, 800, 700, 600, 500, 400, 300, 200 and 100 bp derived from a mixture of PCR products and specifically digested plasmid DNA. This product contains two enhanced bands (1.5 kb and 500 bp) for easy referencing. In addition, two tracking dyes, Xylene cyanol FF and Orange G which mimic the migration of 4,000 bp and 50 bp dsDNA during electrophoresis are also added for real time monitoring.
