Figure Lengend Snippet: Growth curve for E. coli DH5α-pCMV-lacZ . The growth curve based on OD 600 measurements is marked by small black circles and the appropriate best-fit curve is indicated in blue. The harvesting time points T 1 , T 2 , and T 3 are presented as bold big points. The minimum–maximum area, within which the measurement values have to reside, is bordered by the red curve (minimal measured OD 600 value) and the green curve (maximal measured OD 600 value).
Article Snippet: Bacterial strain and plasmids The Escherichia coli strain DH5α (F–Φ80lac ZΔM15 Δ(lac ZYA-arg F) U169 rec A1 end A1 hsd R17 (rK−, mK+) pho A sup E44 λ− thi -1 gyr A96 rel A1) (Source: Plasmid Factory, Bielefeld, Germany) was used as a host strain for transformation of the high copy plasmid pCMV-lacZ (Source: Plasmid Factory, Bielefeld, Germany) as well as the low copy plasmid pSUP 201-3 (Simon et al., ). pCMV-lacZ is a ColE1-derived high copy plasmid for therapeutic pDNA production with a size of 7164 bp.
