1)Microarray,but not RNAseq correlate well with QPCR.
2)Gene expression uniquely determined by RNA-seq is more likely
to be false positive. |
S*********s 发帖数: 304 | 2 感觉RNAseq有很多false positive, QPCR confirm不了 |
l****m 发帖数: 751 | 3 听过一个讲座,human和mouse的一般需求建议用microarray;
其他species,没有完美基因组的,或者有特殊需求,比如想看isoform的建议用RNAseq。
特别少量的用QPCR
实际发文章的时候可能RNAseq更favorable更好接受些。

g*****n 发帖数: 250 | 4 Microarray 和 RNAseq 都属于呼悠类的。半斤八两。但是,从道理上讲,RNAseq更可
靠。用QPCR来确认?QPCR就可靠?要用Northern,大伙都忘了吧? |
M*****n 发帖数: 16729 | 5 I have just done an RNAseq, the preliminary analysis not good. many false
hits. |
f*******a 发帖数: 671 | 6 如果只是做differential expression的话,是不是microarray 更成熟一些呢?
觉得RNA-seq再数据分析中还是有不少问题的。 |
M*****n 发帖数: 16729 | 7 但是RNAseq 数据在那里,你可以reanalyze
microarray就只有这么些gene, 不能发现新gene
genome 不完整的话,都是有问题的。

side by side comparisons. |

Did you perform analysis by yourself? Which pipeline did you use?

k****l 发帖数: 279 | 13 I tried confirming gene expression data from RNA-seq by qPCR, 9 out of 10
correlated very well (e.g., RNA-seq shows 8 fold up regulation), PCR shows 8
-16 fold

s******s 发帖数: 13035 | 14 我觉得microarray主要是做法比较统一, 而seq各实验室手法不一样, 还经常不做
repeat.
不过比如遇到alternative splicing这种, microarray作出来的表达量可能错误百出.

Which pipeline did you use? Tophat,STAR?Deseq or cufflinks,cuffdiff?

z*********8 发帖数: 1203 | 16 I used tophat and cufflinks for mapping(DNAnexus) and DESeq for analyzing
differentially expressed gene. DEseq is very nice for beginners like me. I
dont know any R language, but I was able to use the example script to apply
in my case and get the results that I wanted. For pathway analysis, I used
IPA and metacore. |
