pSB6A5

This is the version 5 of the medium copy (minimal pBR322 origin) BioBrick vector backbone pSB6A1. This means, that the cassettes for the ORI and antibiotic resistance have been minimized (reduction of the size and transcriptional terminators flanking the prefix and the suffix have been added, to trancriptionally insulate the inserted parts from the vector backbone machinery and vice versa. This minimization yielded a reduction in size from 4022 bp to 2743 bp.

For comparison of the copy number of the plasmids, triplicates of OD normalized bacterial cultures containing the respective plasmids were miniprepped. The DNA concentration was then determined by an agarose DNA gel electrophoresis of EcoRI digests of the purified plasmids (Figure 1). This experiment showed a clear reduction in copy number of the minimized version of the original plasmid (Figure 2).
