■ 質(zhì)粒簡介
該質(zhì)粒可用于在雞b-肌動(dòng)蛋白，兔b-球蛋白雜合啟動(dòng)子（CAG）的控制下高效表達(dá)基因，和各種哺乳動(dòng)物細(xì)胞中的人CMV-IE增強(qiáng)子; CAG啟動(dòng)子序列由雞b-肌動(dòng)蛋白啟動(dòng)子，第一外顯子和第一內(nèi)含子的一部分（似乎具有強(qiáng)的增強(qiáng)子樣活性），與兔b-珠蛋白片段連接，由第二內(nèi)含子的3'部分 包括正常拼接反應(yīng)所需的分支點(diǎn)）和第三外顯子的5'部分。
This plasmid is useful for highly efficient expression of genes under the control of the AG promoter and the human CMV-IE enhancer in various mammalian cells.The AG promoter sequence consists of the chicken β-actin promoter, the first exon and part of the first intron (that seems to have a strong enhancer-like activity) linked to a rabbit β-globin fragment, consisting of a 3' part of the second intron (inclusive a branch point which is required for normal splicing reactions) and a 5' part of the third exon.When cloning a fragment downstream from the lac promoter it may be advisable to use lacIq strains in order to prevent fortuitous expression of a possibly noxious polypeptide.
質(zhì)粒只保證關(guān)鍵序列正確，不保證表達(dá)效果。
