I want to establish mammalian cell line (A549 and Vero) expressing T7 RNA polymerase. I've tried to amplify T7 polymerase gene from E. coli DE3 strain but failed. Maybe because the E. coli stock we have at lab is too old.  I'm not sure if it's still DE3 strain inside. Does anyone know where I can buy T7 genome or T7 gene l?

Thank you.
