Figure 3

The expression level monitoring of transformed bacteria after four freeze-thawing cycles at − 70 °C within 90 days. Escherichia coli Bl21 (DE3) containing plasmid pET28a-EGFP was also evaluated without adding the inducing agent to observe the basal expression of the target protein. Data are represented as Mean ± SD from three independent measurements.
