Lysis device sequences were received from Microsynth. Only two reactions worked: those containing primers 1289F and 1333R.
Output (For the reverse primers, the reverse complement sequence is shown):

Irina and Nadine selected the 2 plasmid backbones we will use: J23019 and J61002 (check the parts registry). They have 2 different origin of replication sites and should both have 15-20 copy numbers. Interesting also, they both contain RFP and pTet. We already have them in the freezers, now let's focus on primers design!
Wednesday, 8 June 2011
Lilia and Douglas miniprep'ed the cultures containing the lysis cassette, and sent the plasmids for sequencing.
Three colonies were miniprep'ed: two containing the T4 variant, one containing the lambda variant. This yielded solutions with plasmid concentrations of 221.9 ng/µl for T4 colony 1, 225.5 ng/µl for T4 colony 2, and 57.0 ng/µl for lambda colony. Only T4 colony 1 was sent for sequencing, using the primer solutions prepared on 31 May 2011. Results should be in on Friday.

Sequencing results from Microsynth for the lysis cassette (Biobrick K112808) have arrived. The sequence is entirely covered by the seven reactions, and all but a few bases match. As far as I can tell, this biobrick is valid! (Doug)
The results of a blast, individually querying each of the sequences against the official K112808 sequence are available here: BLAST results.
Sequencing results, for each primer (again, reverse complements shown here for the reverse primers --- those denoted by an "R"):

With help from Henrike, Douglas checked the mistakes in the K112808 (lysis cassette) sequence. On the entire sequence, only 7 errors occurred in several reactions, and are therefore likely to be actual errors in the DNA. They occur in positions (with regard to the original sequence in the registry):
- 70: CTC codon substituded for CTA. Both code for leu, so that position is still valid
The following are missing bases:
- 677 and 684: lie in the junction between sub-bricks K112805 and K112806. Still valid.
- 1199: lies in the junction between K112806 and B0010. Still valid.
- 1387: second base of K112807, in the non-coding region. Still valid.
- 1698: lies in the junction between K112807 and B0010. Still valid.
- 1701: beginning of B0010, in the non-coding region. Still valid.
In conclusion, there is one codon substitution, and six missing bases that all lie within the junction between two bricks or the non-coding region of a brick. Experimentally, the brick does lyse cells in culture. Therefore, the sequence appears valid.

We practised MITOMI with TetR linear template and random DNA sequence + target DNA sequence. We performed ITT (in vitro transcription/translation) on TetR linear template before adding it to the chip. However, the results are disappointing: we have more DNA binding for the random sequence (1000 RFU change) than for the target sequence (500 RFU)...
Images: Green fluorescence comes from TetR (labeled Lysines) and red fluorescence comes from DNA (cy-5 labeled). We can clearly see that the protein amount seems to be the same, whereas the DNA fluorescence is decreased.
Perhaps the ITT doesn't yield a functional TetR, or we didn't have the optimal concentration of binding DNA (too much nonspecific interactions?). We'll definitely continue the MITOMI practise to find out.
