1KB (0.25-10 kb) DNA 分子量标准（包含荧光染料）
DNA Ladder
DM3160 FluoroBand 1KB (0.25-10 kb)预染荧光DNA分子量标记为即用型产品，其预先混和高灵敏度DNA 专一性荧光染料及1 x DNA上样缓冲液，方便用户直接使用。 本产品内含13条经由PCR产物及特定质体DNA剪切而成之DNA预染荧光条带。 此13条DNA条带可直接以光波长470纳米之蓝光或紫外光激发后产生荧光。 此产品于3k及 1k 为增量条带以方便目测并辨别片段大小。 本预染荧光DNA分子量标记内含两种追踪染料Xylene cyanol FF (4,000 bp)及Bromophenol blue (500 bp)以预估条带泳动进度。 若电泳槽配有适当激发光源(蓝光或紫外光)则可实时监控电泳槽内条带分离状况并追踪泳动进度。The DM3160 FluoroBand 1KB (0.25-10 kb) Fluorescent DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with high sensitivity DNA binding fluorescent dye and loading dye for direct loading on gel. The DNA ladder DM3160 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; these bands can be visualized when illuminated with 470 nm blue light or UV light. This product 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. Real time observation of the electrophoresis is also possible if compatible light source is fitted to the electrophoresis tank.
