April 13/2010 (In the Lab: JV, AS)
Objective: Test Restriction Endonucleases for Activity
Relevant Information:
Endonucleases available
EndonucleaseOptimal Buffer**Other Buffers
EcoRVNone2xT(100%); O,G(50-100%)
EcoRIRedO(100%);R(100%)*;2xT(100%)

PstIOrangeR(100%); B,G,T,2xT(50-100%)
DpnITangoB,G(100%): O,R,2xT(50-100%)
*Star Activity
**Optimal Buffer from Fermentas

Use pUC19 plasmid as test, it has cut sites for EcoRI, PstI, XbaI (unsure about BcuI/SpeI, DpnI but will try anyways), and none for EcoRV
Red Buffer: EcoRI, PstI, Control (No Enzyme)
Tango Buffer: BcuI/SpeI, XbaI, DpnI, Control (No Enzyme>

Methods: Set up Master Mixes:
Red MMper tube (µL)Total (µL)
MilliQ H2013.7555
Red Buffer (10x)27
pUC19 (10pg/µL)27
Total19.7569

Tango MMper tube (µL)Total (µL)
MilliQ H2013.7555
Tango Buffer (10x)27
pUC19 (10pg/µL)27
Total19.7569

To each tube, add 19.75µL of master mix and 0.25µL of enzyme
Incubated reaction mixes at 37oC (Start:7:00pm; End:7:45pm)
Add 3.3µL of 6x loading dye to each reaction mixture and load 10µL final volume onto a 1% agarose (in TAE) gel.
Add 1µL of 6x loading dye to 1µL of GeneRuler 1kb ladder (at 0.5µg/µL)
Gel loading order as follows:
LaneSample
11kb Ladder
2Tango Control
3DpnI (Tango)
4BcuI/SpeI (Tango)
5XbaI (Tango)
6EcoRI (Red)
7PstI (Red)
8Red Control
9Empty
10Empty

Ran gel at 100V for 1 hour
Results: pUC19 plasmid DNA not present at a high enough concentration to visualize by ethidium bromide staining (1kb ladder did stain).
Conclusion: Will have to re-run experiment with DNA that is present at high enough concentrations to visualize by ethidium bromide staining


May 5/2010(in the lab: JV)
Objective: Test Restriction Endonucleases for activity (take 2)
Relevant Information:
Plasmid DNA used here will be "ES-pSB-CEYFP" from last year's plasmid stocks
Prefix Enzymes are: EcoRI and XbaI
Suffix Enyzmes are: SpeI and PstI
(JV worked out in lab notebook which buffers would be best for each prefix/suffix enzyme combination)
Reactions will be assembled as follows:
EnzymeBufferVolume MM(µL)Volume Enzyme(µL)
PstIRed19.75.25
XbaITango19.75.25
SpeITango19.75.25
EcoRIRed19.75.25
EcoRI/SpeIRed19.5.25+.25
XbaI/SpeITango19.5.25+.25
EcoRI/PstIRed19.5.25+.25
XbaI/PstITango19.5.25+.25

Make up Master Mixes as follows:
Red MMper tube(µL)Total*(µL)
MilliQ H2015.7586.675
Red Buffer (10x)211
pDNA**211

Tango MMper tube(µL)Total*(µL)
MilliQ H2015.7586.675
Tango Buffer (10x)211
pDNA**211

*Volume per reaction time 5.5 **Unknown concentration of pDNA

Incubated for 70min at 37oC (Start-1:05pm; End-2:15pm)
Added 3.3µL of 6x loading dye to each reaction mixture and loaded 10µL onto a 1% agarose gel (in TAE)
Added 1µL of 6x loading dye to 2µL of gene ruler 1kb ladder
Load order as follows:
LaneSampleVolume Loaded (µL)
1pSB-CEYFP/PstI10
2pSB-CEYFP/EcoRI10
3pSB-CEYFP/EcoRI/PstI10
4pSB-CEYFP/EcoRI/SpeI10
5pSB-CEYFP/XbaI/PstI10
6pSB-CEYFP/XbaI10
7pSB-CEYFP/SpeI10
8pSB-CEYFP/XbaI/SpeI10
9pSB-CEYFP/Red Master Mix Control10
10pSB-CEYFP/Tango Master Mix Control10
11pSB-CEYFP/MilliQ H20 Control10
12Ladder4

Ran gel at 100V for 1 hour

Results:

This gel shows that SpeI does not cut on its own, and does not cut when combined with other enzymes
Conclusion: Test other source of SpeI to see if it has any activity.

May 6/2010(in the lab:KG, AS)
Objective: To check if the old SpeI enzyme (exp date: March 2011) will cleave plasmid DNA, since we believe the newer SpeI enzyme (exp date: 2012) does not.
