Wet Lab
[http://partsregistry.org/Part:BBa_I6007 Inverter TetR (BBa_I6007)] was transformed again. And the new plasmid (created on July the 10th, 10.07.09) LacI-RBS was transformed on DH5-alpha competent cells.
We failed in purifing our [http://partsregistry.org/Part:BBa_B0010 Terminator (BBa_B0010)], do it again tomorrow, beginning with the digestion, etc.
Cloning Strategy
Restriction enzymes on [http://www.neb.com/nebecomm/products/category1.asp?#2 Biolabs website] and [http://www.neb.com/nebecomm/tech_reference/restriction_enzymes/cleavage_olignucleotides.asp clevage oligonucleotides]
TRP promoter biobrick strategy
- Problem to overcome:
- SpeI sites on Trp promoter sequence and it's an upstream part which has to be cut with ES.
- Strategy:
- PCR: Forward primer having E and X sites and Reverse primer NheI.
- Digest Trp promoter with E and NheI.
- Digest plasmid with E and X.
- Ligation -> E site is recreated; X and NheI have compatible ends so ligation is possible and the site is destroyed (mixted site).
