NGS: f02-gc-dec2018.fasta

Cloned DNA: -
Promoter: Human cytomegalovirus immediate early promoter (CMV-IE) and enhancer
Phage T7 gene 10 promoter (T7g10)
binding site:
Terminator: Simian virus 40 polyadenylation signal (SV40 polyA)
Selection marker: Suppressor tRNA gene (supF; requires a p3 containing host)
Replicon: Bacteriophage M13 origin
Escherichia coli plasmid pMB1 origin
Polyoma virus origin
Simian virus 40 bidirectional origin (SV40)
Host range: Escherichia coli; use strains with the p3 helper plasmid (kan resistant, amber codon in amp and tet)
Mammalian cells; SV40 permissive cells
Parental clone: pCDM7
Further information: pCDM8 is a shuttle vector designed for high-level transient expression of cloned cDNA in mammalian cells. The protein encoded by the cDNA can be expressed under control of the human CMV-IE promoter and enhancer and the SV40 polyadenylation site.
The T7 promoter is used for in vitro transcription of the cDNA insert.
The small HIV (human immunodeficiency virus) fragment (29 nucleotides) between the human CMV-IE and the T7 promoter sequences has an enhancer function.
The presence of the polyoma and SV40 origins of replication enables the vector to replicate episomally in mammalian cells expressing large T-antigen (e.g. WOB, COS cells).
The supF tRNA suppressor gene is used for selection in E. coli (MC1061[p3]).
The M13 origin is useful for synthesis of single-stranded DNA upon infection with the M13 helper phage.
The SspI fragment (153 bp) of the 3' UTR region of the SV40 small t-antigen is missing, but without effect on the function of the vector.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727510.1, except for 39 nucleotides spread over the sequence, and a reverse orientation of the supF suppressor gene.
