Tim Weenink

After yesterdays horrible discovery that the I-SceI Homing Endonuclease we got from MIT was actually T4 DNA ligase we had to adjust our cloning strategy. The more primitive part without promoter was found to be the correct one, except that is was assembled with part !A instead of p(LacI). So we did that assembly again today. With p(LacI) from the delay team upstream, *T1 (downstream) and backbone pSB1C3 (also from the delay team). Both RbCl chemically comp and EC electrocomp cells were transformed.

2  !Fr1n upstream 1900 ok, but not needed
3  !Fr1n downstream 1900 ok
4 destination plasmid 3000 ok

!Fr1n downstream will be purified from the gel by gel extraction and used for the new stategy as Tim mentioned before.

Good results on the conjugation test. All plates were imaged on the safe imager with the 5 Megapixel camera. Colony counting was done with [http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1770926 Clono-Counter].
