Our new pSB1A7 cloning vector blocks read-through transcription
To prevent uncontrolled expression of parts within our device, we built insulated cloning vector pSB1A7 (). pSB1A7 was built using the pre-existing vector. The terminators in pSB1A3 are designed to prevent read-through from inside the device out into the vectr (purple arrows) but the vector is not designed to stop read-through into the vector (red arrows). We added double terminators () in opposite orientations at each end of the BioBrick cloning site region to shield the insert from transcription read-through. When the pancakes are cloned into pSB1A7, tetracycline resistance is dependent on the proper orientation of the two DNA pancakes.
