Objective: Set up new ligations of pLacI and sRBS-Lum-dT according to Tom Knight's protocol. Previous ligation had very little DNA.
Relevant Information:
- Want a final mass of 25ng of each pDNA in the ligation mix.
- Final concentration of pDNA in restriction digest should be 25-50ng/µL.
- Tom Knight's restriction reaction is 50µL, therefore there should be 1000ng pDNA in each restriction digest.
- Identified the following plasmids in our working plasmids box:
Common Name Location Concentration (ng/µL) Volume/rxn (µL) pLacI Maxiprep A9 990 ~1 pLacI (B1) A6 440 ~2 sRBS-Lum-dT (2) A1 965 ~1 sRBS-Lum-dT (1) A2 1145 ~1 sRBS-Lum-dT Maxiprep B8 4780 ~.2 sRBS-Lum-dT B7 4375 ~.25 sRBS-Lum-dT (1) G2 335 ~3 sRBS-Lum-dT (2) G3 965 ~2 - Make a 1:10 dilution of sRBS-Lum-dt maxiprep (D8) and sRBS-Lum-dT (B7). 0.5µL pDNA in 4.5µL water.
- Cut pLacI with EcoRI and SpeI
- Cut sRBS-Lum-dT with XbaI and PstI
- Cut pSB1T3 with EcoRI and PstI
- Will have total of 12 ligation reactions, want 12x2µL of pSB1T3 to add to each, therefore want 25µL of pSB1T3.

Continue Ligation on Saturday (See below).
June 5/2010
(In the lab:AS)
Objective: Ligate restriction products from June 3/2010.
Relevant information:
- Have 3 tubes of part 1 (pBad-TetR)
- In ampicillin backbone
- Have 10 tubes of part 2 (fluorescent protein - various)
- In ampicillin backbone
- Will have 30 combinations
- Will use pSB1C3 as plasmid backbone
- Used most of the pSB1T3 and want to save remainder for creating new backbone via PCR.
Method:
*Restriction digests were not heat killed after reactions. Freezing probably killed the restriction enzymes, but I will hea kill them at 80oC for 20 minutes anyways prior to adding Ligase.- Cool on ice for 10 minutes before adding ligase.

2µL DyeRan gel at 100V for 90 minutes.
Results:
No bands visible except for pSB1T3 lanes, therefore could not quantify anything that had not already been quantified.
Also, purification of DNA done on June 7/2010 seemed to reduce amount of pDNA in sample.
Objective: Restrict mms6 (D9,D10) and dT (C1) so we can ligate the dT onto the mms6 coding region.
Method:
mms6 Restriction
- 2µL mms6 pDNA
- 2µL Red buffer
- 0.25µL EcoRI
- 0.25µL SpeI
- 15.5µL MilliQ H2O
dT Restriction
- 2µL dT pDNA
- 2µL Orange buffer
- 0.25µL EcoRI
- 0.25µL XbaI
- 15.5µL MilliQ H2O
Incubated for 1 hour at 37oC
Heat shock on heat block (80oC) for 20 minutes
Ligation- 2µL dT pDNA
- 2µL mms6 pDNA
- 0.25µL T4 DNA Ligase
- 1µL 10x buffer
- 4.75µL MilliQ H2O
Analyze results on 1% TAE agarose gel

Looks like the mms6 DNA was not cut at all. Therefore is doubtful that the ligations will work.
June 8/2010 - Evening
Objective: Transform pLacI-sRBS-Lum-dT constructs assembled via three antibiotic assembly on June 3/2010. Also transform mms6-dT constructs assembled today using old insertion method.
Method: Follow transformation protocol. Results: No colonies anywhere
June 9/2010
(in the lab: TF, JV)
Objective: Transform mms6-dT ligation reactions from June 8/2010.
Method: Followed transformation protocol and transformed the following:- mms6 (D9) + dT (C1)
- mms6 (D10) + dT (C1)
- pUC19 (positive control)
- Water (negative control)
Results: No transformants on plates.

Looks like everything was restricted. Ligations may work this time.
Follow-up: Ligation mixtures can be restriction tested and (if cutting works) transformed into DH5α cells.
Objective: Transform pDNA from distribution plates into DH5α cells to generate glycerol stocks for lab.
Method:
Remove DNA from the following locations on the 2010 distributions kits:- double terminator (B0010-B0010; AKA B0017) from kit plate 2 well 6K (pSB1A2)
- double terminator (B0010-B0012; AKA B0015) from kit plate 1 well 23L (pSB1AK3)
Transform into DH5α cells using transformation protocol, with pUC19 as positive control (1ng/µL), and water as negative control.
Results:
- Positive control: TMTC (too many to count) colonies
- B0010-B0010: 41 colonies
- B0010-B0012: 120 colonies
- Restrict rbs-xylE wit EcoRI and SpeI (Red Buffer)
