Optimized high yield synthetic plasmids
View Patent ↗One aspect of the current invention is an optimized synthetic mammalian expression plasmid with a mutated origin of replication (e.g. “mut” family of plasmids) comprising a therapeutic element, and a replication element. The therapeutic elements of this plasmid are operatively linked and located in a first operatively-linked arrangement. Additionally, the optimized synthetic mammalian expression plasmid comprises replication elements, wherein the replication elements are operatively linked and located in a second operatively-linked arrangement. The first-operatively-linked arrangement and the second-operatively-linked arrangement comprise a circular structure of the codon optimized synthetic mammalian expression plasmid.
1. A synthetic mammalian expression plasmid comprising:
(a) a synthetic or eukaryotic promoter;
(b) codon-optimized-eukaryotic therapeutic gene sequence;
(c) a poly adenylation signal;
(d) a selectable marker gene sequence operably linked to a selectable marker gene promoter;
(e) a ribosomal binding site; and
(f) an origin of replication comprising a sequence that is SEQ ID No.: 39
wherein elements (a)-(c), above are operatively linked and located in a first operatively-linked arrangement; and elements (d)-(f), above are operatively linked and located in a second operatively-linked arrangement.
2. An isolated nucleic acid having an origin of replication comprising SEQ ID No.:39.
