Our team ([http://parts.mit.edu/wiki/index.php/Davidson_2006 Davidson College]) has used this vector in E. coli strain JM109 extensively. Clones are Amp resistant and are recovered in reasonable yields from mini preps. One drawback is that the vector has read-through transcription that comes into the cloned BioBrick part from both directions. This problem is a major one when an "off state" is critical for the control of a device. Parts without a promoter are expressed in this vector, regardless of orientation (see pSB1A7 Part Design for details). Reverse read-through might be from the Amp resistance gene. Forward read-through might be from a cryptic promoter, since no known genes in the backbone are in the plus orientation.

"***WARNING***" The RFP version of this part is actually in pSB1A2 and NOT pSB1A3. This finding has been personally sequenced confirmed in addition to being confirmed in the 2009 QC (look at the VR sequence of the RFP version of this part from the 2009 distribution: QC09_P667_W41590_VR.ab1). This means that the built in terminator is NOT there. The ccdB version appears to actually be pSB1A3 which does contain the terminator. Look [1]here.

"***WARNING***" [http://2009.igem.org/Team:SDU-Denmark We] can confirm the findings of siegeljb, The contents of well 1K in this years distribution plates(supposedly BBa_J04450 in pSB1A3) is in fact BBa_J04450 in pSB1A2.!!! I'm going to do a write up of the data showing this, but until then i can be contacted through the Wiki.
