(In Lab: JV)

Objective: Isolate plasmid DNA of RBS-xylE (BBa_J33204) from DH5α cells and confirm results.

Method: "Mini-prep" the plasmid DNA using boiling lysis miniprep. Then restrict the DNA once and run on a 1% agarose gel (TAE).

June 2/2010 - Evening

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.

Method:
Restriction

Incubated at 37^oC for 75 minutes.

Used Red buffer for the EcoRI/SpeI and EcoRI/PstI digests
Used Tango buffer for the XbaI/PstI digests
Did not heat kill upon removal from incubation, put directly into -20^oC fridge.

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 80^oC for 20 minutes anyways prior to adding Ligase.

- Cool on ice for 10 minutes before adding ligase.

Master Mix	Volume/tube (µL)	Total Volume (µL)
DNA	6	---
10x Buffer	1	32
T4 DNA Ligase	.25	8
MilliQ H₂O	2.75	88

Add 4µL master mix to each DNA tube.

Follow-up: Ligation reactions will be transformed into DH5α cells
