Applied Biosystems TaqMan RNA-to-CT 1-Step 试剂盒可为各种Assay提供一致的 RNA 靶标定量,并已通过 Applied Biosystems TaqMan 基因表达Assay综合文库进行验证。推荐该试剂盒用于各种应用,包括一般基因表达研究、生物标记物发现和微阵列验证。

TaqMan RNA-to-CT 1-Step 试剂盒的特点包括:
可在宽动态范围内进行精确测量,并确保可靠的性能
•已通过 TaqMan 基因表达Assay验证,实验设置简单
•在各种靶标之间保持一致的性能,包括富含 AT、富含 GC 的序列及长序列
•1-Step形式意味着更少的移液步骤,减少了发生错误的机会

在不同加样浓度范围内的效率
RNA 模板加样量的较大灵活性使得您可在广泛模板量范围内实现出色的实时荧光定量 PCR 效率。图1显示了跨越6个数量级的卓越扩增效率。结果与 TaqMan RNA-to-CT 2-Step 试剂盒的结果相当,而且,相对于 TaqMan One-Step RT-PCR Master Mix 试剂,在动态范围和灵敏度方面有着明显的改进。

在低靶标浓度下实现高灵敏度
TaqMan RNA-to-CT 1-Step 试剂盒已通过使用拷贝数确知的合成 RNA 模板进行验证。在测定低浓度靶标时会出现明显的采样误差,因此需要使用多次重复实验进行统计分析,以便进行正确评估。图2显示了靶标的预期数量和相应的平均 CT 值。统计分析表明,基于 T 检验(表 I),样品定量具有高置信度,其结果与少至10个靶标拷贝的结果一致*。

*结果取决于多种因素,包括Assay设计。

常见问题解答 (FAQ)

What can I do to improve the sensitivity of my qPCR assay?

If you are targeting a low-abundance gene, you may have trouble getting Ct values in a good, reliable range (Ct > 32). To increase the sensitivity of the assay, you may want to consider the following:

- Increase the amount of RNA input into your reverse transcription reaction, if possible
- Increase the amount of cDNA in your qPCR reaction (20% by volume max)
- Try a different reverse transcription kit, such as our SuperScript VILO Master Mix, for the highest cDNA yield possible
- Consider trying a one-step or Cells-to-CT type workflow (depending on your sample type)

How do I set the baseline for my qPCR experiment?

Most times your instrument software can automatically set a proper baseline for your data. Check out our short video, Understanding Baselines, for more information on how to set them (https://www.youtube.com/watch?feature=player_embedded&v=5BjFAJHW-bE).

How do I set the threshold for my qPCR experiment?

In most cases your instrument software can automatically set a proper threshold for your data. Check out our short video, Understanding Thresholds, for more information on how to set them (https://www.youtube.com/watch?feature=player_embedded&v=H_xsuRQIM9M).

I am not getting any amplification with my TaqMan Assay or SYBR Green primer set. What is causing this?

There could be several reasons for no amplification from an assay or primer set. Please see these examples and suggested solutions in our Real-Time Troubleshooting Tool (https://www.thermofisher.com/us/en/home/life-science/pcr/real-time-pcr/qpcr-education/real-time-pcr-troubleshooting-tool/gene-expression-quantitation-troubleshooting/no-amplification.html) for more details.

I am getting amplification in my no-template control (NTC) wells in my qPCR experiment. What is causing this?

There could be several reasons for amplification in a NTC well. Please see these examples and suggested solutions in our Real-Time Troubleshooting Tool (https://www.thermofisher.com/us/en/home/life-science/pcr/real-time-pcr/qpcr-education/real-time-pcr-troubleshooting-tool/gene-expression-quantitation-troubleshooting/amplification-no-template-control.html) for more details.
