This SMOBio ExcelBand XL 25kb DNA Ladder (cat# DM4100) is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct loading on gel. The broad range DNA Marker DM4100 is composed of 14 individual DNA fragments: 25k, 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1k, 750, 500, and 250 base pairs derived from a mixture of PCR products and specifically digested plasmid DNA.
This SMOBio wide range 25 Kb DNA ladder DM4100 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.
