Sequence Analysis

Lysis cassette

Lysis cassette and heat inducible promotor

S15b: (Lysis cassette K124014) is named K124017 in the registry Part without RBS at the beginning Part without antiholin the sequece is also mutated leading to wrong amino acids if combined with RBS there would be too many bases (8) between RBS and coding sequence part is likely to be not effective

green light receptor

CcaR

S17: (CcaR with Prefix and RBS) is ok. Check RBS. S18: seems to be ok too.

red light receptor

pycA+terminator

S24: prefix and suffix not complete

cph8

S29: Sequence without part. Has to be done again.

Project Name:

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:

Documentation:

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


3A Assembly of linearized empty Tet Vector Psb1T3, PR Parts S39, S43 (CM resistance) and GFP Pbd from PCR with P18,19,20

I did not digest linearized PsB1T3 with Dpn.

Run a gel to verify if the part is cut out. 12.07.2011 freiburg.jpg

blue light receptor

LOV1

S33: LOVtap only

LOV3

S35: is K322999. This sequence is the LOVtap with the tryptophane promoter, RBS, mRFP and two terminators.
