Design Notes
The BioBrick standard vectors are designed to be easy to use for their most common purpose: assembly of BioBrick standard biological parts. To meet this requirement, we included BBa_P1016 within the BioBrick cloning site. BBa_P1016 encodes the positive selection marker ccdB. Positive selection markers prevent one of the most common problems during assembly of BioBrick parts: contamination of the ligation reaction with uncut plasmid DNASambrook-2001. Any cells transformed with the uncut plasmid DNA produce the lethal protein ccdB and dieBernard-Gene-1994 Bernard-Gene-1995 Bernard-Biotechniques-1996. Note, however, that the drawback of this solution is that inclusion of this part requires that users propagate both the base vector and any derived vectors in E. coli strains tolerant of ccdB expression such as DB3.1Bernard-J-Mol-Biol-1992 Miki-J-Mol-Biol-1992.
