Rescue experiments with genomic DNA from stably transfected cells

Plasmid	HEK293	TE-671
pEPito-hCMV/EF1-EGFP-IRES-BSD	3/3	3/3
pEPito-hCMV/EF1-EGFP-IRES-BSD-ΔSMAR	0/9	0/9
pEPito-hCMV/SM22-EGFP-IRES-BSD	0/9	3/3

First number: number of rescue experiments where plasmid DNA could be rescued without any rearrangement from the isolated chromosomal DNA. Second number: total number of performed rescue experiments. ‵0′ indicates that no clones could be obtained in any rescue experiment.
