A Premature Termination of Human Epidermal Growth Factor Receptor Transcription in Escherichia coli

Figure 1

GST-EGFR expression in E. coli BL21 strain. The proteins were separated in a 10% SDS-PAGE and stained with Coomassie blue. (Lanes 1 and 2) Two clones of E. coli BL21 cells transformed by empty pGEX-6P-1 vector. (Lanes 3–6) Different clones of E. coli BL21 cells transformed by pGEX-EGFR. (Lane M) The protein masses of the BioRad markers are indicated in kDa. The arrows point to GST and the 50 kDa protein.
