RACE(rapidamplification－of－cDNA－ends)技術2
具體的實驗步驟cDNA第一條鏈的合成：我們建議進行cDNA合成的對照反應，這樣可以對樣品的 cDNA的合成進行鑒定。加入各種試劑之后，在氣浴中42度保溫一個小時。注意： 在水浴或酒精浴中保溫回減少反應體積，從而降低第一鏈的合成效率。將管放于冰上，以終止第一鏈的合成反應。直接進行第二鏈的合成。cDNA
RACE(rapidamplification－of－cDNA－ends)技術1
RACE技術的簡介cDNA完整序列的獲得對基因結構、蛋白質表達、基因功能的研究至關重要。完整的cDNA 序列可以通過文庫的篩選和末端克隆技術獲得。末端克隆技術是20世紀80年代發展起來的。RACE(rapid-amplification of cDNA ends)是通過PCR進行cDNA末端快速克隆
