The invention provides materials and methods for the detection of nucleic acid expression via the 3′ portion of expressed sequences. Embodiments of the invention include the use of microarrays comprising nucleic acid probes that are complementary to the 3′ end of expressed sequences and by the use of quantitative PCR (Q-PCR) based amplification of sequences found at or near the 3′ end of expressed sequences. The invention may be used to detect the presence of expressed nucleic acids encoding particular gene products (sequences present in a “transcriptome”).
本发明提供了通过表达序列的 3′部分检测核酸表达的材料和方法。本发明的实施方案包括使用由与表达序列 3′端互补的核酸探针组成的微阵列,以及使用基于定量 PCR(Q-PCR)的方法扩增在表达序列 3′端或附近发现的序列。本发明可用于检测是否存在编码特定
基因产物的表达核酸(存在于 "转录组 "中的序列)。
