From: Development of new plasmid DNA vaccine vectors with R1-based replicons
Comparison of specific yields of different vectors. Specific yields of pCP40 (parent plasmid), pVAX1-GFP (pUC-based DNA vaccine vector), and pDMB02-GFP (R1-based DNA vaccine vector) with and without a temperature shift from 30°C to 42°C are shown. Times in the legend refer to hours after the temperature shift, and error bars represent the standard deviation calculated from duplicate flasks.
