低分子量 DNA Mass Ladder(专利待决)适于通过溴化乙锭染色估计未知 DNA 样品的质量(量)(1)。 这种 ladder 用专门构建的质粒制备,由六种 100 至 2000 bp 的平端片段以等摩尔的量混合而成。 4 µl 低分子量 DNA Mass Ladder 的电泳得到分别含有 200、120、80、40、20 和 10 ng(总共 470 ng)DNA 的条带。
原厂资料:
Low DNA Mass Ladder (patent pending) is suitable for estimating the mass (quantity) of unknown DNA samples by ethidium bromide staining (1). Prepared from a specially constructed plasmid, the ladder consists of an equimolar mixture of six blunt-ended fragments from 100 to 2,000 bp. Electrophoresis of 4 µl of Low DNA Mass Ladder results in bands containing 200, 120, 80, 40, 20, and 10 ng (470 ng total) of DNA, respectively.
Contents and Storage
Low DNA Mass Ladder is supplied at 10 mM Tris-HCl (pH 7.5), 1 mM EDTA. Store at -20°C.
