Figure 3From: A combined in vitro / in vivo selection for polymerases with novel promoter specificitiesGrowth characteristics of cells containing wild-type autogene. Cells containing the wild-type autogene (pET/T7p/T7) were grown at 37°C and induced with IPTG at an OD600 of 0.5 (indicated by the arrow). The OD600 was monitored every 15 min for 15 hours using an automated Microbiology workstation Bioscreen C (Labsystems Oy, Finland).Back to article page
