特点

  • 创新的疏水性、低粘度的PCR封装屏障
  • 保证real-time PCR等应用获得高成功率
  • 无需使用管帽,加快反应体系构建

产品详情

Vapor-Lock是一种创新的疏水性、低粘度的PCR密封介质。只需10 µl易于吸取的Vapor-Lock就可形成有效的屏障。Vapor-Lock覆盖反应液,可避免蒸发,且无需管盖。与矿物油不同,Vapor-Lock不会污染或抑制PCR反应。

绩效

使用Vapor-Lock覆盖反应液无需管盖。在比较CT值的实验中,有管盖的反应与无管盖使用Vapor-Lock覆盖的反应,得到的结果相同(参见" Vapor-Lock eliminates need for tube caps")。

小反应体积(如384孔板中的反应体积)通常重复性不好,而且在很多real-time仪器上都很难成功运行。然而,Rotor-Gene Q实时荧光定量PCR分析仪在运行时可持续离心样本,使反应液保持在管底部(参见" Principle of Vapor-Lock")。处理小反应体积时,避免蒸发非常重要。Vapor-Lock可防止蒸发,已成功用于低至5 µl的反应体系的扩增(参见" Successful amplification using small reaction volumes")。

原理

进行热循环时,反应液可能蒸发,导致反应体积和反应组分浓度的变化。Vapor-Lock可阻止蒸发,在定量real-time PCR和高分辨率熔解(HRM)等精确应用中保证高成功率。Vapor-Lock的外观和性能像水溶缓冲液。它位于水相上层,在水相的上方形成一层(参见" Principle of Vapor-Lock")。Vapor-Lock低粘度、低比重,允许超过约1 µl体积的液滴轻松穿过Vapor-Lock层,进入下层的水相中。

在联管或多孔孔板中处理众多样本时,需要较长的反应体系构建时间,这增加了样品蒸发的可能性,可能导致实验无法成功。Vapor-Lock完全无需管盖,可加快反应体系构建。Vapor-Lock覆盖样本,防止蒸发,提高结果的可靠性。

与矿物油不同,Vapor-Lock不会污染或抑制PCR反应。Vapor-Lock的背景荧光不超过一个荧光单位(参见" Minimal autofluorescence of Vapor-Lock")。

Vapor-Lock可与QIAgility仪器完全兼容,用于高精确度、自动化的反应体系构建。Vapor-Lock非常适合与Rotor-Gene Q实时荧光定量PCR分析仪配合使用。

程序

Vapor-Lock可用于手动和自动化反应体系构建。推荐在加入各种反应组分之前向反应管中加入Vapor-Lock。Rotor-Gene Q实时荧光定量PCR分析仪运行时的轻微离心,可使Vapor-Lock和水溶反应组分完全分成两层(如Vapor-Lock在上层,反应混合液在下层)。如果不使用Rotor-Gene Q实时荧光定量PCR分析仪,我们推荐在循环之前对样本稍加离心。

应用

Vapor-Lock适合于PCR和HRM应用,包括:

  • 基因表达分析
  • 基因分型
  • 突变筛选

FAQ

If Vapor-Lock is used to overlay PCR reactions, which volume should be entered as reaction volume in the Rotor-Gene Q Software?

The reaction volume to be entered in the Rotor-Gene Q software should be the sum of the PCR reaction volume and the volume of Vapor-Lock.

 

 

FAQ ID -2150
Can Vapor-Lock be used with samples processed on the QIAgility?

Vapor-Lock is fully compatible with the QIAgility instrument for high-precision, automated reaction setup. It is also highly suited for use with the Rotor-Gene Q cycler. For support to program your QIAgility instrument for use with Vapor-Lock, please contact your local QIAGEN Technical Support Department.
