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

June 3/2010 - Evening

Objective: Repeat restriction of pSB1T3 and ligate with pLacI and sRBS-Lum-dT. Previous ligations all used up on gel.
Method:

Follow-up: Inoculated 5mL LB media (tetracycline positive) with cells from the transformation plates and incubated at 37^oC overnight. (June 5/2010).

Objective: Ligate pBad-TetR part with fluorescent protein part in pSB1C3 backbone.

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

Ran 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.

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

(In the lab: TF, DM, HS)
Objective: Restriction Digest of RBS-xylE with EcoRI and SpeI

Method:

Restriction Digestions

Pipetted 15.5µL of water, into 2 reaction tubes (0.6mL) each.
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 (37^oC) for 1 hour.
Placed in ice for 10 minutes.

Objective: Test Ligations of rbs-xylE with T4-Ligase from iGEM -20^oC and from HJ's lab's -20^oC.

Method:

Pipette 12.75µL of Milli-Q H₂O into 4 mincrocentrifuge tubes.
Pipette 2µL of 10X T4-Ligase buffer into all 4 tubes.
Pipette 5µL of the RD product into both iGEM ligase tubes and HJ-Lab Ligase tubes.
Pipetted 5µL of the RD control into both iGEM ligase tubes and HJ-Lab ligase tubes.
Incubate overnight

Ran gel at 100V for 82 minutes.

Result:The gel "broke" while running. Jeff hypothesized the cause to be excessive heat. However, the DNA was still visible.IMAGE TO COME!!!!

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.

(In the lab: AS)

Adam: not convinced that the rbs-xylE was cut properly last night. There doesn't appear to be and band where the insert should be.

Objective: To confirm that EcoRI & SpeI are cutting (also PstI). Use rbs-xylE as test plasmid DNA.

Method: Digest rbs-xylE with the following enzyme combinations:

EcoRI + SpeI (old [i.e. John's]) + Red Buffer
EcoRI + SpeI (new) + Red Buffer
EcoRI + PstI + Red Buffer
EcoRi + Red Buffer
SpeI (old) + Tango Buffer
SpeI (new) + Tango Buffer
PstI + Red Buffer
No enzyme controls (Red & Tango Buffer)

Reaction mix as follows:

Milli-Q H₂O 15.5µL
10X Buffer 2µL
pDNA 2µL
Enzymes 0.25µL + 0.25µL

Incubated at 37^oC for 1 hour . Analyze on 1% TAE Agarose gel as follows:

June 16/2010

(in lab: JV) Objective: To miniprep Adam's overnight cultures of xylE and rbs. Completing this will give us a working stock of this plasmid.

Method: Use the boiling lysis miniprep protocol and pufrify using BioBasic protocol for purification of PCR products.

Objective: Transform pLacI-sRBS-lumazine synthase-dt into BL21(DE3).

Method:

Followed transformation protocol

Changes to the protocol include:

Added 5µL DNA to 50µL BL21(DE3).
Incubated in 500µL SOC instead of 250µL LB
incubated for 90 minutes at 37^oC at 4:30pm.

Results: There wasn't any growth after overnight incubation. Possibility of an antibiotic mix-up.

June 17/2010

(in lab: ADS)

Objective: Continue with ligation test. Use restriction products to test T4 DNA ligase.

Method: Have 10µL of DNA remaining for each restriction. Ligate together one of the single cut reactions, and ligate one of the double cut reactions. 4µL of each sample will be tested against each ligase.
i.e.

EcoRI +SpeI (new) cut vs HJ's ligase
EcoRI + SpeI (new) cut vs iGEM ligase
SpeI (new) cut vs HJ's ligase
SpeI (new) cut vs iGEM ligase

Reaction Mixture:

DNA -> 4µL
10X Buffer -> 2µL
Milli-Q -> 13.5µL
Ligase -> 0.5µL

Prior to setting up reaction, heat kill restriction enzymes by heating to 80^oC for 20 minutes and subsequently cooling on ice for 10 minutes.

Ligations begun at 6:50pm

Will run samples at 30 minutes reaction time and overnight.

Analyze ligations in a 1% TAE Agarose gel

Lane	Sample	Load (µL)
1	No Enzyme Control (from last night)	1 DNA solution + 1 Dye + 4 H₂O
2	EcoRI + SpeI (old)(from last night)	1 DNA solution + 1 Dye + 4 H₂O
3	EcoRI + SpeI (new) vs HJ's Ligase	5 DNA solution + 1 Dye

6	SpeI (new) vs iGEM ligase	5 DNA solution + 1 Dye
7	SpeI (old)(from last night)	1 DNA solution + 1 Dye + 4 H₂O
8	1kb Ladder	0.25 Ladder + 4.75 H₂O + 1 Dye

No observable ligation occurring 30 minutes with both ligases.

Objective: Prepare DNA for sequencing
