Part:pSB1A2

pSB1A2 (Replaced by pSB1A3)

pSB1A2 is a high copy number plasmid carrying ampicillin resistance. The replication origin is a pUC19-derived pMB1 (copy number of 100-300 per cell).

pSB1A2 has one terminator upstream of its MCS, which is oriented to prevent transcription from *inside* the MCS from reading out into any DNA outside the MCS. The orientation of the pBLA promoter driving the AmpR gene is such that relatively little transcription should be coming into the MCS from upstream. Ideally, a future version of the standard biobrick vectors would have terminators bracketing an MCS that were 100% efficient in terminating both into and out of the MCS region.
