In this study, we have developed a ribosomal binding site (RBS) switching strategy for direct cloning of PCR fragments. RBS is an A/G rich region upstream of the translational start codon and is essential for gene expression. Change from A/G to T/C in the RBS blocks its activity and thereby abolishes gene expression. Based on this property, we introduced an inactive RBS upstream of a selectable marker gene, and designed a fragment insertion site within this inactive RBS. Forward and reverse insertions of specifically tailed fragments will respectively form an active and inactive RBS, thus all background from vector self-ligation and fragment reverse insertions will be eliminated due to the non-expression of the marker gene. The effectiveness of our strategy for TA cloning and blunt end ligation are confirmed. Application of this strategy to gene over-expression, a bacterial two-hybrid system, a bacterial one-hybrid system, and promoter bank construction are also verified. The advantages of this simple procedure, together with its low cost and high efficiency, makes our strategy extremely useful in HTP cloning constructions. ¹Ø¼ü´Ê KeyWords Plus OSITIVE-SELECTION VECTORS; PCR PRODUCTS; ESCHERICHIA-COLI; BACILLUS-SUBTILIS; IN-VIVO; GENE; RECOMBINATION; SEQUENCE×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Chen, SY (ͨѶ×÷Õß) ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ Chinese Acad Sci, Wuhan Inst Virol, Key Lab Agr & Environm Microbiol, Wuhan, Peoples R China. µØÖ·: ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 1 ] Chinese Acad Sci, Wuhan Inst Virol, Key Lab Agr & Environm Microbiol, Wuhan, Peoples R China ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 2 ] Chinese Acad Sci, Grad Univ, Beijing, Peoples R China µç×ÓÓʼþµØÖ·:sychen@wh.iov.cn »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ National Natural Science Foundation of China 31170133 National Transgenic Program of China 2011ZX08009-003-001-003 ²é¿´»ù½ð×ÊÖúÐÅÏ¢ ³ö°æÉÌ PUBLIC LIBRARY SCIENCE, 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Àà±ð / ·ÖÀà Ñо¿·½Ïò:Science & Technology - Other Topics Web of Science Àà±ð:Multidisciplinary Sciences ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000311821000189 PubMed ID: 23185557 ISSN: 1932-6203 ÆÚ¿¯ÐÅÏ¢ Impact Factor (Ó°ÏìÒò×Ó): Journal Citation Reports® ÆäËûÐÅÏ¢ IDS ºÅ: 047ER Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 30 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 0 |
