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重组酶产品说明

纯度： 通过色谱法纯化所有重组酶以获得高百分比纯度。酶通常纯度大于90％。用于制备酶的重组克隆已经是DNA序列以确认与野生型酶的同一性（确保重组酶没有突变）。我们不测定酶污染酶。因此，在购买大量批次之前，客户应在小规模上测试酶对特定应用的适用性。Bayou Biolabs生产的酶“按原样”提供给客户 提供： 酶以甘油缓冲液供应。酶在干冰上运输，费用由客户承担。请参阅下表了解目前可用的酶。 批量： 批量购买，价格低廉。标准批量为100毫克，500毫克，1克，5克和10克。我们还可以打包客户指定的任何批量。我们有能力扩大生产数百克的批次。请联系客服了解价格和供货情况。
