最近在看NGS (next generation sequencing) 的一些網站, 其中一個中文網站認為 NGS可以取代Microarray, 這就是我不懂之處, Microaray 是幫助我們了解 gene expression 在不同樣本間比較 (比如有病 VS 健康) NGS是分析genomic at sequence-base 兩種方法對我而言目的不同, 如何討論"取代" -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 115.64.9.214

People can use NGS to sequence cDNA or mRNA.

By mapping the sequence reads to reference genome,

we can directly count the number of reads from

each gene. I personally prefer this over micro-

如樓上 可以去查一些 RNA-seq 的 review paper 看看

去思考一下NGS如何產生data 以及它的量和品質就可以知道

是可以取代,但是NGS價格實在太貴了...
