This part was seen work in practice. Synthesis of the four encoded polypeptides in very small scale cultures (1 ml) was observed by 35-S-Methionine labelling (Figure 1).

Results

E. coli was transformed with BBa_K562007 expressed from pT7.5, and the plasmid pGP1-2 encoding T7 polymerase, and grown aerobically for 3 hours in LB medium. T7 polymerase synthesis was induced by heat shock before all native transcription in E. coli was halted by the addition of rifampicin. 10 minutes later 1 ml of cells was then collected and spiked with 35-S-labelled Methionine. Following a 10 minute incubation the cell pellet was harvested and resuspended in Laemmli disaggregation buffer. Protein labelling was analysed by SDS-PAGE and autoradiography.

This very small scale and sensitive technique reveals all polypeptides being expressed from the plasmid.
