Fig. 3From: Development and comparison of cell-free protein synthesis systems derived from typical bacterial chassisScreening of competent cells and DNA concentrations in E. coli, B. subtilis, C. glutamate and V. natriegens CFPS systems. a E. coli CFPS system. b B. subtilis CFPS system. c C. glutamicum CFPS system. d V. natriegens CFPS system. The data were normalized. The mean and standard deviations are shown (N = 3). The number "1" of the normalized treatment represented the optimal fluorescence value of each factor in each CFPS systemBack to article page
