pBBR1MCS-5 plasmid extraction


Vladimir helped me by making a plasmid pBBR1MCS-5 extraction from 4 different colonies: colony 1, colony 2, colony DH5α, colony S17. I ran a gel to see if the extraction were OK. I conclude that the extraction was succesfully done, the plasmid from S17 was the most concentrated.


I ran the gel with this characteristics:

  • 120 V
  • 35 min
  • 4μL template + 3.5μL dye each lane.

Gel analysis

All the marks are visible and in the correct place (between 4000 and 5000 bp) so I conclude that the extractions were good. The plasmid that is more concentrated is the one extracted from S17 (7th lane). The marks that are visible a little bit up the main marks are isoforms (concatenations for example).


The tubes are in my rack, the next step is to make a PCR from this parts to extract the plasmid backbone.
