green light receptor

transformation with reporter parts

Investigators:Julia

transformation with iGEM parts BBa_I15016 which is B0032.ECFP
and BBa_I15017 which is B0032.EYFP.
Tomorrow the green light promotor from PCR of 29_August should be inserted infront of the reporter proteins CFP and YFP.

again ligation as last time (02.08.11)

Lysis cassette

Troubleshooting of the modified Lysis genes K124017

Investigators:Theo


Minipreps of the first inoculations were applied on a 1% agarose gel without digesting them to see if they have an insert of the modified Lysis genes K124017. Nr1, 5 and 7 were sent for sequencing since the size seems to be about right.

  • Note: S4 is the B0034 RBS (ribosome binding site), S15 is the non-modified K124017 Lysis Cassette without RBS

Procedure


PCR tube:

total volume 20 μl


  1. add H2O (17 μl -X-Y-Z)
  2. add 2 μl Ligase Buffer 10x
  3. add Insert 1, Insert 2(when proceeding from 3A digestion use 2 μl of each)
  4. add Vector (20ng needed. When proceeding from 3A digestion use 2 μl)
  5. Add 1 μl T4-DNA Ligase
  6. Incubate 10-30 min at room temperature
  7. heat for 20 minutes at 80°C
  8. store at -20°C or directly proceed to transformation

Continue from Digestion Date 31.08. Name Rüdiger

Experiment

Project Name: Precipitator

Procedure


  1. add H2O (38μl-DNA )
  2. 5 μl NEB4 buffer (stored at iGEM’s, -20°C)
  3. 5 μl 10x BSA (used 1:10 diluted sample stored at iGEM’s, -20°C)
  4. DNA (500 ng) (Vector:Insert ratio 1:3 in following Ligation)
  5. 1 μl restriction enzymes (stored at iGEM’s, -20°C)
  6. heat for 1-2 hours 37°C (6 hours if time)
  7. heat for 20 minutes 80°C (inactivation of enzymes)
  8. keep at 4°C if you cannot continue

Measured DNA-concentration with Nanodrop to calculate the volume of DNA to do the digestion:


Sample Name DNA concentration (μg/μl)

Why are you doing this experiment? Where are the samples stored? Antibiotica resistance, vector used etc.


Repeated digeston from 31.08..

Run a gel to verify if the part is cut out.
