■ 質(zhì)粒簡介
pET28GST-LIC質(zhì)粒是一個大腸桿菌表達(dá)載體，T7啟動子驅(qū)動GST和融合表達(dá)一起表達(dá)，載體上有SacB致死基因，可通過5%蔗糖來篩選陽性克隆。
The pET28GST-LIC vector was derived from expression plasmid pET28a-LIC (SGC) by inserting the GST-tag from pET41a (Novagen) into the XbaI and NcoI sites. It is used for T7 promoter driven expression of recombinant proteins with the addition of a 242 amino acid N-terminal fusion tag containing the 217 amino acid GST-tag protein followed by a 6X His followed by a thrombin cleavage site. Two stop codons are included in the vector at the C-terminal cloning site.Insertion of DNA sequence into the cloning/expression region is preformed using BD-Biosciences Infusion enzyme mediated directional recombination between complementary 15 nucleotide DNA sequences at the ends of the insert (PCR product) and BseRI linearized vector. Insertion of target sequence involves replacement of a SacB gene stuffer sequence, which provides for negative selection of the original plasmid on 5% sucrose.
