发帖数: 4984 | 27 Microarray实际上是一个在淘汰边缘的技术，不知道你从哪里得来越来越多大学医院要
使用Microarray技术？ 我去年在一家专做Microarray疾病诊断的公司做过一年多。事
实上一个检测的成本非常高，大约是600-700美元。一块定做的Affy芯片是60几块，但
是要上到Hybridisation的话，前期要使用一些生物试剂作mRNA-cDNA-ssCNDA
amplification, 这个试剂盒5000美元一个，只能做50个反应，还有Consumables都很贵
，还有人工等等。你看看Affymetrix的股价从2000年140多块跌倒现在8块多就是一个好
的证明。现在诊断技术很多，即便用到分子诊断，Microarray也不是首选，基本上是RT
-PCR，便宜，速度快。千万不要去想每天多少人怀孕，多少人去做某项检测。我手上好
的检测技术和项目一大堆，也曾经编织过类似的美梦，但到中国去了解了一下，要解决
SFDA，医保问题，还有物价局的定价。另外现在如果不是非常有必要的检测项目，孕妇
们未必会去做，她们不傻，也会从网上去阅读有关内容。

Abstract
The production of biocontrol factors by many pseudomonads is reported to be
controlled at post-
transcriptional level by the GacS/GacA signal transduction pathway. This
involves RNA- binding translation repressor proteins, RsmA and RsmE, and the
small regulatory RNA(sRNAs) RsmX, RsmY and RsmZ .While the former represses
