The DM2100 ExcelBand™ 100 bp DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct gel loading. The DNA ladder DM2100 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 easier reference. 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. 


  • Sharp bands

  • Quick reference enhanced bands 

  • Ready-to-use— premixed with loading dye for direct loading

  • Stable— room temperature storage over 6 months

DNA fragments with identical in size are indistinguishable on agarose gels, but, on acrylamide gels, even slight differences in DNA sequence can lead to noticeably different migration rates. To provide increased intensity of DNA marker/ladder bands, multiple DNA fragments with identical in size but different in DNA sequences are used. SMOBIO's AccuBand™ series DNA markers (DM1200, DM2000, DM2200 and DM2400) are more suitable for DNA PAGE.
