分离基因组中表达的低丰度转录物仍然是转录组研究中的一个严峻挑战。用于分析的方法的灵敏度直接影响检测的效率。我们比较了EST方法和SAGE方法,以确定哪一个更敏感,以及在何种程度上的灵敏度是大的低丰度转录本的检测。使用两种方法检测到的相同的低丰度转录本作为靶序列,我们观察到SAGE方法比EST方法检测低丰度转录本的灵敏度高26倍。SAGE方法在检测低丰度转录本时比EST方法更有效。
Isolation of low-abundance transcripts expressed in a genome remains a serious challenge in transcriptome studies. The sensitivity of the methods used for analysis has a direct impact on the efficiency of the detection. We compared the EST method and the SAGE method to determine which one is more sensitive and to what extent the sensitivity is great for the detection of low-abundance transcripts. Using the same low-abundance transcripts detected by both methods as the targeted sequences, we observed that the SAGE method is 26 times more sensitive than the EST method for the detection of low-abundance transcripts. The SAGE method is more efficient than the EST method in detecting the low-abundance transcripts.
