blue light receptor

already done:

  1. Transformation of Lov-Tap in cells.


To-do:

  1. Cloning of promotor (medium) in Lov-Tap part and perform a transformation. Plating out of the cells on trypthophan-free medium.


Quick change

Investigators: Theo

already done:

  1. repressor part (BBa_K098995) has no bases between RBS (B0034) and start codon (K098997), resulting in no translation.
    • quickchange of the repressor part to insert 6bp between RBS and start codon

To-do:

  1. DpnI digestion to digest the DNA template (methylated DNA) of the PCR to have only the new synthesized DNA strand.
  2. After digestion with DpnI, transformation of cells with the corrected part (BBa_K08995)

Experiment

Project Name: Correct number of nucleotides between RBS and ATG of temp. sensitive repressor from Lysis Device

Procedure


  1. take cells from -80°C freezer and put them on ice! (every eppi contains about 400 μl cells)
  2. thaw cells on ice 20 minutes
  3. pipette 50 μl cells and 2 μl DNA into eppi still on ice!
  4. Incubate for 30 minutes on ice
  5. Heat at 42°C for 60 sec
  6. Incubate on ice for 5 minutes
  7. Add 200 μl LB Broth
  8. Incubate for 2 hours at 37°C (cells with lysis cassette at 30°C!!)
  9. Plate 50 μl and 200μl on two different LB/Agar plates with appropriate antibiotic resistance

Documentation:

Why are you doing this experiment? Name of the sample? Where are they stored? Name the vector with inserts, antibiotika resistance etc.


It was done in ordert to correct the number of nucleotides between RBS and ATG of the temperature sensitive repressor from our Lysis Device, ie to insert 6bp.


It didn’t work because the false DNA Template was taken (S15 - K124014 - instead of S11 - K098995 -).


This will be corrected by doing another Quickchange using S11 (ie K098995) as template.

Continue from Experiment (Date)PCR 1507

(Name) Ruediger

Project Name:

GFP Pbd

PCR-Mixture for one Reaction:

For a 50 µl reaction use


32,5µl H20
10µl 5x Phusion Buffer
2.5µl Primer fw
2.5µl Primer dw
1µl dNTPs
1µl DNA-Template
0.5 µl Phusion (add in the end)

What program do you use?

10x (95C-41/52C-72C) + 25x ((95C-60C-72C)


How did you label the PCR-Product, where is it stored and what do you do next?


Reactions:

lane 1

quick load braod range marker

lane 2

empty

lane 3

P28+P18+M14.1

lane 4

P28+P19+M14.1

lane 5

P28+P20+M14.1


Results:

did not work well.

Strange band size in lane 3. 4 and 5 did not work.
