Figure 3. Production of different membrane proteins using the cell-free system.

Figure 3

After synthesis of the membrane proteins in the cell-free system in the presence of FluoroTect GreenLys tRNA, the membrane fraction was precipitated and separated by SDS/PAGE. (A) 10% polyacrylamide gel; lane 1, AtKC1 (plant, K+ channel, 6 transmembrane segments (TMS)); lane 2, KAT1 (plant, K+ channel, 6 TMS); lane 3, KAT2 (plant, K+ channel, 6 TMS); lane 4, GORK (plant, K+ channel, 6 TMS); lane 5, AKT1 (plant, K+ channel, 6 TMS); lane 6, NhaA (bacteria, Na+/H+ antiporter, 10 TMS); Lane 7, AspT (bacteria, aspartate: alanine antiporter, 10 TMS); lane 8, MsbA (bacteria, ABC transporter, 12 TMS). (B) 15% polyacrylamide gel; lane 9, Sec61 β(human, 1 TMS).
