产品详情

QuickLyse Miniprep Kit 提供了一种基于离心柱的快速方法,用于分离测序级质粒 DNA。在单一缓冲液中实现细菌细胞重悬、裂解和 DNA 结合,只需极少的手动操作时间即可实现快速 DNA 纯化。

绩效

QIAGEN QuickLyse Miniprep Kit 采用单步裂解技术,可超快制备多达 15 µg 的质粒 DNA。DNA 的质量可确保在测序、限制性酶切分析和克隆等应用中获得可靠性能(见图“ 可重现的产量”)。

QuickLyse Miniprep Kit 可为任何下游应用(包括测序)生产足量的质粒 DNA(见图“ 自动测序中较长的读长”)。 可从 1.5 ml 细菌培养液中获得多达 15 µg 的高拷贝质粒 DNA(见图“ 高质量质粒 DNA 的产量高”)。分离出的质粒 DNA 的 OD260/280 比率为 1.7–1.9,表明其质量和纯度适合所有敏感应用。可轻易实现超过 700 个碱基的测序读长。

原理

与大多数采用三步裂解程序的方案不同,QuickLyse Miniprep Kit 将酶促和渗透过程相结合,只需 3 分钟即可单步裂解细菌细胞。此外,QuickLyse 技术使用的缓冲液更少,简化了操作,节省了时间:可在不到 22 分钟的时间里完成 24 次质粒 DNA 小提。

程序

细菌细胞重悬后裂解,DNA 在单一缓冲液中结合,只需极少的手动操作时间即可快速纯化 DNA。3 分钟的裂解步骤后,澄清裂解物即可直接应用于 QuickLyse Spin Column。质粒 DNA 与柱膜结合,并在单一洗涤步骤后接受洗脱(见流程图“ QuickLyse 程序”)。分离出的 DNA 可直接用于标准应用,包括自动测序、PCR、限制酶切分析和克隆。

应用

QuickLyse Miniprep Kit 可为任何下游应用(包括自动测序)生产足量的质粒 DNA。

常见问答

Can the bacterial pellet in the QuickLyse Miniprep procedure be resuspended by pipetting up and down or shortening the vortexing time?

No. Vortexing for 30 seconds as described in the QuickLyse Miniprep Handbook is absolutely critical to resuspend and lyse the bacterial cells. Failure to follow this step will result in greatly reduced DNA yields.

 

FAQ-1352
How can I increase the DNA yield from low-copy plasmids using the QuickLyse Miniprep Kit?

When using the QuickLyse Miniprep Kit, the addition of 125 µl isopropanol to the lysate, prior to transferring it to the QuickLyse Spin Column, may increase plasmid DNA yield in some cases.

 

FAQ-1354
Is it possible to elute plasmid DNA obtained with the QuickLyse Miniprep Kit in nuclease-free water?

Yes, nuclease-free water may be used for the elution of plasmid DNA purified with the QuickLyse Miniprep Kit. However, for higher DNA stability and optimal yields, it is recommend to elute using the provided elution buffer (Buffer QLE).

 

FAQ-1355
What is the composition of elution buffer QLE in the QuickLyse Miniprep Kit?

Elution Buffer QLE of the QuickLyse Miniprep Kit contains 10 mM Tris-Cl and 0.1 mM EDTA (pH 8.5). Due to the very low concentration of EDTA, enzymatic downstream reactions such as PCR and cycle sequencing are not inhibited.

 

FAQ-1356
What volume of bacterial culture can be processed using the QuickLyse Miniprep Kit?

Normally, 1.5 ml bacterial culture is used with the QuickLyse Miniprep Kit. Only if the OD600 is < 2.0, up to 3 ml culture may be used. Growth in LB medium is strongly recommended. Growth in nutrient-rich media, such as 2xYT, is not recommended.

 

FAQ-1357
What is the largest plasmid size that can be purified using the QuickLyse Miniprep Kit?

The QuickLyse Miniprep Kit can be used for plasmids up to 9 kb in size. It is not recommended for Large-Construct purifications.

FAQ-1752
3311 - Can QuickLyse miniprep kits be used with QIAVac 24 Plus?
No, this is not possible since the columns do not fit properly on the QIAVac 24 Plus manifold and the vacuum is not strong enough.
