摘要
不断发展的研究技术对黄曲霉RNA的提取质量提出更高的要求,而真菌的细胞壁结构及其内源性RNase活性常是达到这一目标的主要障碍。以黄曲霉菌丝为材料,探讨了采用TES热酚法获得高质量总RNA的方法,并通过RT-PCR(反转录聚合酶链式反应)和RNA-Sequencing(转录组测序)对获得的RNA进行了质量验证。结果显示,TES热酚法不但所用试剂价格低廉,该法所提取的RNA质量较高,其浓度、纯度和完整性均可满足RT-PCR、转录组测序的文库构建和高通量测序等对RNA要求较高的分子生物学实验。
The rapidly developing molecular techniques require the ability to extract high quality RNA from Aspergillus flavus. The cell wall structure and endogenous RNase activity in A. flavus are often the main obstacles for obtaining RNA with high quality. In this paper, TES hot phenol method was applied to obtain total RNA from A. flavus, and the total RNA was further used in RT-PCR （ Reverse translation-polymerase chain reaction） and RNA-sequencing. The results showed that the TES hot phenol method can be used to get a good quality of total RNA from this filamentous fungus as templates for following studies, such as RT-PCR and RNA sequencing.
