SMOBIO ExcelBand 1Kb DNA Ladder is a ready-to-use DNA ladder which covers DNA fragment size from 0.25-10 kb (DM3100). ExcelBand 1Kb DNA ladder is pre-mixed with loading dye for direct loading on gel.
The SMOBIO DNA marker DM3100 is composed of 13 individual DNA fragments: 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1k, 750, 500, and 250 bp derived from a mixture of PCR products and specifically digested plasmid DNA. This DM3100 DNA marker contains two enhanced bands (3 kb and 1 kb) for easy referencing. In addition, two tracking dyes, Xylene cyanol FF and Bromophenol blue which mimic the migration of 4,000 bp and 500 bp dsDNA during electrophoresis are also added for real time monitoring.
Phenol extracted PCR products and dsDNA digested with specific restriction enzymes, equilibrated in 10 mM Tris-HCl (pH 8.0) and 10 mM EDTA.
