ORF filtering vector. The filtering vectors features are shown in panel A. Blunt ended gDNA random fragments are cloned between a leader sequence (Sec, SRP, or TAT) and the mature β-lactamase gene. C-terminal SV5 and His tags are used for detection and purification respectively. In panel B, the effect of selective pressure on ampicillin is shown for ORFs and non ORFs.
