載體描述

pETDuet-1載體被設計用來在大腸桿菌中同時表達兩個外源基因. 載體含有兩個多克隆位點，每一個多克隆位點是通過T7啟動子/Lac操縱子和一個核糖體結合位點組成。pETDuet-1攜帶有pBR322質粒來源的ColE1復制子, lacI基因和氨芐抗性基因。

本載體可以與pACYCDuet-1載體聯合使用，在合適的宿主菌中，可以一起共表達至多4個目的基因。插入在pETDuet-1載體多克隆位點1的目的基因可以使用pET Upstream Primer (Cat. No. 69214-3)和DuetDOWN1 Primer (Cat. No. 71179-3)進行測序，插入在多克隆位點2的目的基因可以通過DuetUP2 Primer (Cat. No. 71180-3)和T7 Terminator Primer (Cat. No. 69337-3)進行目的基因測序。

pETDuet?-1 is designed for the coexpression of two target genes. The vector contains two multiple cloning sites (MCS), each of which is preceded by a T7 promoter/lac operator and a ribosome binding site (rbs). The vector also carries the pBR322-derived

ColE1 replicon, lacI gene and ampicillin resistance gene. This vector can be used in combination with pACYCDuet?-1 (Cat. No. 71147-3) in an appropriate host strain for the coexpression of up to 4 target genes. Genes inserted into MCS1 can be sequenced using the pET Upstream Primer (Cat. No. 69214-3) and DuetDOWN1 Primer (Cat. No. 71179-3). Genes inserted into MCS2 can be sequenced using the DuetUP2 Primer (Cat. No. 71180-3) and T7 Terminator Primer (Cat. No. 69337-3)
