Size (kb): 11.3170003890991200
Vector: pECV25 (plasmid)
Promoters: Promoter RSV LTR
Construction: pRSVneo, p205
Construct size (kb): 11.31700038909912
Features: marker(s): ampR, hygR, G418R
promoter: RSV LTR
replicon: pMB1, EBV oriP
terminator: beta-globin polyadenylation
contains sequence nuclear antigen 1
Restriction digests of the clone give the following sizes (kb): HindIII/SacI--5.7 (doublet); SalI--11.5; XhoI--11.5.
Shuttle expression vector maintained episomally in human cells at a copy number of 25 - 50. Shows high transfection efficiency and can be introduced as supercoiled plasmids.
Vector can be rescued from transfected cells with no detectable rearrangements.
The EBNA-1 gene contains an in-frame deletion of a repetitive region of 700 +/- 20 bp. This deletion increases the number of stably maintained plasmid molecules per cell.
The order of the major features in this plasmid is: bla (ampR) - hph (hygR) - RSV LTR - HindIII - rabbit beta-globin intron splicing signals - NotI - agpt (G418R) - XhoI - rabbit beta-globin polyadenylation signal - SalI - oriP - SacI - EBNA-1 - ClaI.
