Using different amounts of HEK293T total RNA as templates, the DNA fragment of 197bp of the β-actin gene was detected. The electrophoresis results of RT-PCR amplification after adding a specified amount of this product or similar products from Company T (competitor) in a 50μl reaction system are shown in the figure. As shown in the figure, this product has a consistent detection sensitivity compared to Company T's products, and can sensitively detect RNA as low as 1pg, and has better specificity and amplification efficiency.

*如果模板具有复杂二级结构或高GC区域,可将反应温度提高至55℃,有助于提高产量。
**退火温度需要根据引物退火温度调整,一般设置成低于引物退火温度1 ~ 2℃即可。
Guidelines
1. 使用DEPC处理研究中使用的所有设备,或购买经证明无核酸的设备。在研究过程中戴上手套,并经常更换,以避免RNA酶污染。
2. 确保所用试剂中没有RNA酶污染。
3. 通常情况,28~30个循环可达到最佳扩增,对于低拷贝目的基因的检测,可将循环数增加到40个。
4. 使用本试剂盒进行反转录反应时必须使用特异性的反转录引物,Random Primer、Oligo dT Primer不能使用。
5. 实验操作时应将酶制品放在冰上,实验结束后立即保存在 -20°C。
