ABSTRACT

 * Purification of pBBRMCS5 of BL21_DE3 cells.


 * Because of the plasmid that Pablo and I extracted yesterday was so dirty, today I isolate more. Pablo left cultures of BL21_DE3 cells to grow overnight. I follow the protocol of the following link: [[User:Paulina_Alatriste/Notebook/UNAM_Genomics_Mexico_2011/2011/06/14| Plasmid isolation].
 * Miguel told us that maybe the plasmid was dirty because the Solution III is not working properly so today I use another one, and also in step 5 after adding TE 10:1 I vortex the tubes to resuspend the pellet. I did an electrophoresis gel to see the quality of the plasmid:




 * Lanes 2-5 are the isolated plasmid. As you see is again dirty with chromosome residues so on Monday we will extract more using a Kit.
