高纯度质粒 DNA PureLink™ HiPure 质粒小提试剂盒设计用于在 1.5 - 2 小时内从大肠杆菌中高效分离出质粒 DNA。试剂盒采用由孔径均匀的小颗粒组成的阴离子交换树脂将质粒 DNA 纯化至相当于两次通过 CsCl 梯度的水平(图 1)。无需采取额外步骤去除污染物(如苯酚、氯仿和 CsCl),可较大限度地减少有害材料的暴露和处理。
高得率和高效内毒素去除 在克隆高拷贝数质粒时,PureLink™ HiPure 质粒小提试剂盒可在约 1 小时内从 1-3 mL 过夜大肠杆菌培养物中纯化高达 30µg 的高质量质粒 DNA,内毒素水平为 0.1-1 EU/µg(表 1)。通常,当在 Tris-HCl(pH 值为7.5)中稀释样品时,使用 PureLink™ HiPure 质粒 Miniprep 试剂盒分离的 DNA 的 A260/A280 > 1.80,表明 DNA 不含可能干扰下游应用的蛋白。
分离的 DNA 可用于多种下游应用: 纯化 DNA 为超纯级,适用于多种下游应用,包括需要较高纯度 DNA 的应用,如哺乳动物转染(图 2)、自动和手动 DNA 测序、PCR 扩增、体外转录、细菌细胞转化、克隆和标记。

No evidence of persisting measles virus in peripheral blood mononuclear cells from children with autism spectrum disorder.
Authors:D'Souza Y, Fombonne E, Ward BJ,
Journal:Pediatrics
PubMed ID:17015560
'OBJECTIVES: Despite epidemiologic evidence to the contrary, claims of an association between measles-mumps-rubella vaccination and the development of autism have persisted. Such claims are based primarily on the identification of measles virus nucleic acids in tissues and body fluids by polymerase chain reaction. We sought to determine whether measles virus ... More
Evidence of antibiotic resistance gene silencing in Escherichia coli.
Authors:Enne VI, Delsol AA, Roe JM, Bennett PM,
Journal:Antimicrob Agents Chemother
PubMed ID:16940095
The possibility that unexpressed antibiotic resistance genes are carried by bacterial genomes is seldom investigated. Potential silencing of the resistance genes bla(OXA-2), aadA1, sul1, and tetA carried on the plasmid pVE46 in a recent porcine isolate of Escherichia coli was investigated following oral inoculation of the strain into organic piglets. ...

Role of LRAT on the retinoid isomerase activity and membrane association of Rpe65.
Authors:Jin M, Yuan Q, Li S, Travis GH,
Journal:J Biol Chem
PubMed ID:17504753
Absorption of a photon by a vertebrate opsin pigment induces 11-cis to all-trans isomerization of its retinaldehyde chromophore. Restoration of light sensitivity to the bleached opsin requires chemical re-isomerization of the chromophore via an enzyme pathway called the visual cycle. The retinoid isomerase in this pathway is Rpe65, a membrane-associated ... More
