check most of core facilities' price list, and talk to them. Actually, they are almost the same price, less and less people use microarray now.
【在 l***y 的大作中提到】 : 列一下价格对比?

depend on what are you doing. what you talking about is the bio-marker test for some target therapy drug, but actually, the precis therapy ( personalized therapy ) using chemo-drug or cocktail drug (combining different chemo-drug or chemo/target drug) might be based on genomic mutation profile using PDX animal model test and bio- big data on big PDX/patient cohort. This is the real challenging topic for precis therapy. you can quantify the DNA amplification/deletion using ArrayCGH and you can also find SNP using tiling array. what you said are not the key differences between array technologies and next generation sequencing.

what you said is the academic set-up "只要忽悠到下一笔钱,我会立刻 move on". Actually, what I said is the real big biophama R&D projects, all the things are business driven.
【在 n******7 的大作中提到】 : 这个图似乎有些问题 : 1.microarray data 为啥也有RPKM值? : 2.很明显microarray data 的range很小,不是很可比 : 3. CoV是SD除以mean,mean值小的时候就容易特别大了。一个低表达gene,两次测到1 : 个reads,两次测到4个reads,reads的CoV是0.69,so what? (RPKM同理)

if relevent to quantivie analysis of TF binding sites and chromatin accessibility, first microarray then NGS might be a sutiable choice. pls refer
PMID 23739687 Shu H, et al., (2013). Measuring Arabidopsis chromatin accessibility using DNase I-polymerase chain reaction and DNase I-chip assays. Plant Physiol. 162: 1794-801. Abstract DNA accessibility is an important layer of regulation of DNA-dependent processes. Methods that measure DNA accessibility at local and genome-wide scales have facilitated a rapid increase in the knowledge of chromatin architecture in animal and yeast systems. In contrast, much less is known about chromatin organization in plants. We developed a robust DNase I- polymerase chain reaction (PCR) protocol for the model plant Arabidopsis ( Arabidopsis thaliana). more pls go to below both figures or http://www.ncbi.nlm.nih.gov/pubmed/23739687
