Yet another insertion of the mgtc gene into the pKSII+ plasmid

Kamil


Tasks:

  • Plasmid assembly

Methods:

  • The ligation mix was prepared as follows: 1ul plasmid, 3ul gene, 1ul ligation buffer B (Fermentas), 1ul T4 DNA ligase (Fermentas), 1ul 30% PEG, 1ul 10mM ATP, the solution was topped up with H2O to the final volume of 10 ul. The ligation was carried out in 37°C for 1h and then inactivated for 15min. at 65°C.

  • A 200ul batch of chemocompetent bacteria was transformed with 3ul of ligation mix and incubated on petri dishes containing LB medium supplemented with ampicilin, X-gal and IPTG.

  • UPDATE: No luck this time, back to the drawing board...

    Yet another attempt at obtaining a specyific Llo PCR product for fusion with the secretion signal

    Kuba


    PCR was preformed on a product of classical biobrick-format Llo (reamplification)


    three reactions were preformed, each with increasing concentration of template


    • Methods:

      • PCR mixture's composition: 2,5ul pfu buffer (Fermentas), 2,5ul MgSO4 (Fermentas), 1,5ul primers, 1,5ul dNTPs (10 mM), 0,5ul pfu turbo polymerase, 1ul template DNA from Listeria, solution was topped up with H2O to 25ul. <p>One of the samples also contained 1 ul of DMSO</p>
      • PCR programs:
      •  4min 95°C <br>(30s 95°C, 40s 41°C, 1min40s 72°C)x3 <br>(30s 95°C, 40s 44°C, 1min40s 72°C)x28  10min 72°C <br>~ 7°C
      • Electrophoretic separation on 1% agarose gel


      <p>Results:

      • Gel (from left)
      1. GeneRuler DNA Ladder Mix #SM0333 (Fermentas)
      2. sample no.1 (1ul of 100-fold diluted template)
      3. sample no. 2 (2ul of 100-fold diluted template)
      4. sample no. 3 (1ul of template)
