Getting ready for punctual mutation


  • Today, I inoculated E. coli strains containing a plasmid with a constitutive promoter so that, after 6-7 hrs of incubation at 37°C, I can extract the plasmid and ligate the luciferase and double terminator with it.


  • I also did a restriction with Xba I and Pst I for a total of 30μL as follows:


-H2O -------> 18μl

-Buffer 2 --> 4μl

-BSA ------> 1μl

-DNA -------> 5μl

-XBA I -----> 1μl

-PST I ------> 1μl

  • Restrictions were incubated at 37°C for 4 hr and labeled as: lucif + TT c/rbs + 1 purif restr. XBA y PST Mar and the date in the top of the eppendorf.



  • I also ran a gel at 90V for 50min to quantify the ligation PCR product with the mutated RBS to know how to prepare the mix for the PCR with Pfx.
