50 bp DNA 分子量标准
DNA Ladder
DM1100 ExcelBand 50 bp DNA分子量标记为直接使用型产品，内含17条DNA 条带，为方便目测，于500及200 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Orange G，以实时监控并模拟50 bp 双链DNA条带泳动进度。The DM1100 ExcelBand 50 bp DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct loading on gel. The DM1100 DNA marker is composed of 17 individual DNA fragments: 1.5k, 1.2k, 1k, 900, 800, 700, 600, 500, 450, 400, 350, 300, 250, 200, 150, 100, and 50 bp derived from a mixture of PCR products and specifically digested plasmid DNA. This product contains two enhanced bands (500 bp and 200 bp) for easy referencing. In addition, the low range Orange G tracking dye mimics the migration of a 50 bp dsDNA during electrophoresis is also added for real time monitoring.
