100 bp+3K DNA 分子量标准
DNA Ladder
DM2300 ExcelBand 100 bp + 3K DNA分子量标记为直接使用型产品，内含12条DNA 条带，为方便目测，于1.5 k及 500 bp 两条带增量，以快速辨别片段大小；并已预先混合1 x DNA上样缓冲液与追踪染料Xylene cyanol FF及 Orange G，以实时监控并模拟4,000 bp 及50 bp双链DNA条带泳动进度。The DM2300 ExcelBand 100 bp+3K DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct loading on gel. The DM2300 DNA ladder is composed of 12 individual DNA fragments: 3k, 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.
