pET30acer_dFTN2

The pET30acer_dFTN2 vector enables T7 RNA polymerase-based expression of FTN2, which is a humanized Fab that neutralizes tumor necrosis factor α. For FTN2 translocation into the periplasmic space, the light chain (LC) and the heavy chain (HC) of the Fab were fused to the DsbA signal sequence (dsbA_SS), which directs the transport of the fused protein across the plasma membrane into the periplasm using the SRP pathway. doi: 10.1002/BIOT.201800637.

Transcription termination is initialized by the strong terminator tZenit, consisting of 3 single termination loops. More precisely, tZenit includes a synthetically improved T7 terminator (T7T UUCG), a rrnBT1 termination sequence, and a native T7 terminator. doi:10.1021/sb5000115.

The cer element provides additional stability by preventing the formation of plasmid di- and multimers via recombination events catalysed by host cell enzymes. doi: 10.1002/j.1460-2075.1988.tb02884.x.

The plasmid DNA was purified from Escherichia coli NEB5α and consists of 6783  bp (MW ~ 4.2 x106 Da).
