Figure 3. Translation of unnatural codons in CHO cells.
A. Average EGFP fluorescence signal (total fluorescence signal divided by the number of EGFP-positive cells) of CHO cells transfected with unnatural codons with or without cognate tRNAs (and self-pairing tRNA for codon AGX) measured by flow cytometry. *P < 0.05, **P < 0.005, ***P < 0.0005 (two-tailed paired t test). B. The protein shift assay for CHO cells transfected with indicated components. Representative gels from 3 biological replicates.
