感受態(tài)細(xì)胞的制備是基因重組中一項(xiàng)基本技術(shù),是獲得高質(zhì)量基因文 庫(kù)的關(guān)鍵。由于誘導(dǎo)細(xì)菌進(jìn)入感受態(tài)的機(jī)制尚不完全清楚,且感受態(tài)細(xì)胞的轉(zhuǎn) 化率受諸多因素的影響,實(shí)驗(yàn)室之間差異較大。尤其在室溫較高時(shí),感受態(tài)制 備的效果很不穩(wěn)定,摸索高溫季節(jié)制備高效感受態(tài)細(xì)胞的方法仍十分必要。此 外,高效感受態(tài)細(xì)胞貯存不當(dāng)會(huì)很快喪失其感受性,如何較好地貯存感受態(tài)細(xì) 胞亦是一個(gè)亟待解決的問題。制備感受態(tài)細(xì)胞的方法很多,而CaCl2法是目前 實(shí)驗(yàn)室制備感受態(tài)細(xì)胞較為常用的方法之一。   感受態(tài)細(xì)胞圖
