Description: The Exonuclease-It™ plasmid purification system is designed to selectively digest linear chromosomal DNA contamination in a plasmid preparation, without significantly degrading any supercoiled plasmid (or any covalently closed circular plasmid). Exonuclease-It™ will also degrade open circular plasmid and circular single stranded DNA. The Exonuclease-It™ enzyme reagent contains a proprietary mixture of exonucleases to accomplish this task. In a typical 6 hour incubation, Exonuclease-It™ will reduce the amount of chromosomal DNA contamination in a plasmid preparation by 98 percent. The by-products of the exonuclease digestion are deoxynucleoside monophosphates. The Exonuclease-It™ plasmid purification system is ideally used as an added step in any plasmid purification method, in order to thoroughly remove chromosomal DNA. This kit contains sufficient reagents for purifying 150 mg of plasmid. Exonuclease-It™ is not for use in purifying plasmid for human therapy. bayoubiolabs pUC and M13 DNA产品说明   低价格的pUC和M13 DNA 高度纯化：纯度适用于所有分子生物学应用。不含RNA，蛋白质，核苷酸，RNase和DNase污染。pUC质粒实际上是纯超螺旋形式，含有小的切口质粒和染色体DNA污染。进一步纯化M13双链质粒以除去所有残留的单链噬菌体DNA，其可干扰转化。M13单链噬菌体DNA适合作为双脱氧测序应用的对照模板。 价格便宜：比其他供应商便宜 7到45倍。 提供：所有pUC质粒和M13噬菌体以1.0ug / ul浓度提供在TE缓冲液中。以0.50μg/μl浓度提供M13质粒。   价钱 目录 描述 $ 150 P-101 pUC18质粒，1,000微克 $ 150 P-102 pUC19质粒，1,000微克 $ 150 P-103 pUC118质粒，1,000微克 $ 150 P-104 pUC119质粒，1,000微克 $ 150 P-105 M13mp18质粒，100微克 $ 150 P-106 M13mp19质粒，100微克 $ 150 P-107 M13mp18单链噬菌体DNA，500微克 $ 150 P-108 M13mp19单链噬菌体DNA，500微克
