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.

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.

- Pipetted 2µL of red buffer into each of them.
- Pipetted 2µL of rbs-xylE plasmid DNA into both tubes, but taking only the thawed liquid on the side.
- Because this was not proper protocol for aliquoting DNA, we thawed the DNA out completely and then put 2µL more of the rbs-xylE plasmid DNA in.
- Pipetted 0.25µL of EcoRI enzyme and 0.25µL of SpeI enzyme into the restriction reaction tube.
- Placed in incubator (37oC) for 1 hour.
- Placed in ice for 10 minutes.

Objective:Isolate plasmid DNA from DH5α cells.
Method:The plasmid DNA is:
- 1)double terminator B0017 (B0010-B0010) from 2010 kit plate 2:6K pSB1A2
- 2)double terminator B0015 (B0010-B0012) from 2010 kit plate 1:23L pSB1AK2
This will give us 2 additional dt's (3 total) into our working plasmid box to ligate onto the end of our constructs.
Used the boiling lysis miniprep protocol and elute with 50µL of Milli-Q H2O with RNAse A.
These plasmids (labeled 1 & 2 above) are in:
- working plasmid box: 1). J9 2). J10
- glycerol sotck 2010 box: 1). F2 2). F3
DNA was then purified using the protocol for purification of PCR products (BioBasic). DNA was eluted with 35µL of elution buffer.
