SDS-PAGE of bacterial samples with the tat_GFP_RFP (ER1) and tat_ProteinG construct
In order to determine if Protein G is produced in the S3-2B sample and wheater a GFP-RFP dimer is produced in the ER1 sample, a SDS-PAGE was performed. Liquid cell culture with ER1 (tat_GFP_RFP construct), S3-2B (tat_ProteinG construct) and wildtype ER2566 ''E.coli'' cells was centrifuged and the pallet was mixed with SDS loading buffer. This mix was then heated at 95 °C for 15 minutes. The SDS-PAGE results can be viewed in the figure below

SDS-PAGE of bacterial samples with the tat_GFP_RFP (ER1) and tat_ProteinG construct
A new test on the Pm/XylS promoter was performed with the same conditions as earlier.
