RapidIsolationandPurificationofPhotosystemIChlorophyllBinding...
The available procedures for isolation and purification of photosystem I (PSI) from Chlamydomonas reinhardtii are time consuming and usually require several hours of sucrose gradient ultracentrifugation steps. This may lead to structural and functional impairment, including release of pigments and/or dissociation of protein subunits. Moreover, it is difficult to isolate intact complexes from thylakoids cont......阅读全文
RACE(rapidamplification－of－cDNA－ends)技术1
RACE技术的简介cDNA完整序列的获得对基因结构、蛋白质表达、基因功能的研究至关重要。完整的cDNA 序列可以通过文库的筛选和末端克隆技术获得。末端克隆技术是20世纪80年代发展起来的。RACE(rapid-amplification of cDNA ends)是通过PCR进行cDNA末端快速克隆
