BioBrick standard vectors are also designed to be easy to purify. To meet this requirement, we included a pUC19-derived origin (BBa_I50022) in addition to the ccdB selection marker within the BioBrick cloning site of BioBrick standard vectorsVieira-Gene-1982 Norrander-Gene-1983 Yanisch-Perron-Gene-1985. The high copy origin encoded by BBa_I50022 means that both base vector DNA and any derived vector DNA are easily purified in large quantities, irrespective of whether the vector replication origin is low copy or notCabello-Nature-1976 Ioannou-Nat-Genet-1994. Cloning a BioBrick part into the BioBrick cloning site removes the high copy origin in the cloning site thereby restoring replication control to the vector origin.
BBa_I50022 was originally designed as BBa_I50020. However, several introduced mutations to the pUC19 origin sequence rendered BBa_I50020 nonfunctional as a replication origin. Hence, these introduced mutations were reverted to make BBa_I50022, a functional high copy replication origin.
