LOOKS LIKE LIGATION WORKED!!! The initial check showed that there was a band at ~4500 (plasmid), a band at ~2000 (new part) and a band at ~1000 (old part).  So, cells were transformed with the new part and plated.  It seems like 1:2 molar ratio of plasmid to insert worked the best (brightest new part and faintest old part)

+
-
 
+
-
We began the ligation procedure using I0500 (2005) and J06801 (2006).  We were only able to get J06801 to work so we proceeded with the quantitation of that part only.  We obtained 3.0 ng/uL of purified J06801 DNA ready to be ligated tomorrow.

'''Guidelines for Plate-test:'''
 +
<ol>
 +
    <li>On an Amp plate, make 4 sectors (500 uL?) with varying arabinose (0.02%, 0.2%, 2%, 20%) and making sure they don’t touch each other (otherwise diffusion will happen and they’ll be the same concentration), let the arabinose area dry.
 +
    <li>Take o/n of UT3-DH5a and take out 200 uL and add 800 uL of fresh LB and incubate for 1 hr.
 +
    <li>Spin down the cells at 3000 RPM for 5 min and remove 800 uL of supernatant.  Resuspend cells with the remaining 200 uL and gently spread onto plate
 +
</ol>
-
We tested the newly prepared MPs as well as two of the parts from yesterday using a double digest (XbaI and SpeI with Buffer 2).
+
'''Guidelines for Temperature-test:'''
 +
<ol>
 +
    <li>Put a constant amount of arabinose (either 0.02% or 0.2% - don’t want TOO much repression) in each dilution.
 +
    <li>Grow dilutions at 37C until the absorbance is ~0.6 using the GFP ABS program.  Then take some tubes out and put 1 mL into an Eppendorf tube.
 +
    <li>Use the white filter caps and put them on each Eppendorf tube (to allow air in, but to protect against contamination)
 +
    <li>Set mixer to the equivalent to the shaker in the incubator (remember it’s a smaller tube, so there probably needs to be more force on it to get it to shake).
 +
    <li>Set temperature to 22C
 +
    <li>Check the absorbance after a couple of hours and prepare the samples when the absorbance matches the absorbance of the tubs in the incubator (these should be ready before the 22C ones are ready)
 +
    <li>Hopefully we’ll see a significant difference in fluorescence: cold should fluoresce less than hot.

With a lot (a LOT) of help from Seema, we now have 24 Eppendorf tubes of competent cells (DH5a-z1) in the -80C freezer.  We also have ~10 plates with Ampicillin (Amp), ~8 plates with Kanamycin (Kan), and 4 plates with Amp/Kan resistance.  Seema also sorted out our iGEM box and separated between the 2005 parts and the 2006 parts as well as grouped the enzymes, reagents, and ladders.
+
== October 15, 2006 ==
-
Due to a lot of problems with previous attempts at transformations and quantifications, we decided to begin testing the enzymes as well all the part lengths so that we can get a handle of what we have to work with.  So we tested all the enzymes, (EcoRI, XbaI, SpeI, and PstI) using a test plasmid.  In theory, the uncut plasmid should move farther in the gel than the cut plasmid because the circular plasmid is more compact and would better be able to move through the agarose gel.  This was indeed the case and all the enzymes cut successfully as shown the by the 4 bands being at the same height above the uncut band.

'''Charles:'''
 +
<ul>
 +
    <li>Made o/n of the newly plated UT2 2/4 and UT3 7 as well as UT2/UT3 freezer stock

</ul>
-
One thing to note was that the enzyme Xba1 worked slower than the others.  Since the idea was to just check if the enzymes were working, we didn’t need to let the enzymes cut for the full 1 hr (as per the protocol).  Thus, we ran the gel about 40 min early and saw two bands (one for each of the cut and uncut plasmid) in the Xba1 lane.

'''To-Do List:'''

    <li>Make sure the cells fluoresce by diluting in IPTG

Hey team,
+
== October 14, 2006 ==
-
It looks like we'll soon be underway and get to start building and testing parts.  I seem to remember Farshid saying he and Jessica already extracted the parts that we needed from the registry, so that we can move on from there.  There's a semi-final outline of what we'd like to do on the Critical Design Review (CDR) page so take a look at that.  Once we get approval from Prof. Davies, we can get started.
+
'''Charles, Jovan:'''
 +
<ul>
 +
    <li>Mini-prepped UT2 2/4 and UT3 7
 +
    <li>Transform UT2 2/4 and UT3 7 into DH5a-z1 and DH5a cells
 +
    <li>Continue with the IPTG test for the rest of the colonies that we weren’t able to test
 +
        yesterday
 +
</ul>
-
The overall idea is to "assign" a part to a member so that member is responsible for growing/maintaining that part as well as adding that part to someone else's part.  Also, depending on other people's thoughts on this, it would be a good idea to double up on the parts so that we get at least two cracks at making a part at the same time.  This allows everyone to participate in the process from start to finish.  Of course there will be a lot of flexibility in who does what, but this gives us some sort of baseline to start with.  I'll be making some sort of sign-up sheet so if you want to make a specific part for some reason you can.  I was thinking of using Google calendar to help with the coordination, so if you want a Gmail address, you can just email me and I can invite you (Gmail is actually really good).  I'll keep you updated on this idea though.
+
'''To-Do List:'''
-
 
+
<ul>
-
Finally, <b>CHECK THE WIKI REGULARLY!!</b>  We are now going to start doing stuff so there should be regular postings on the Wiki and so I don't want to flood everyone's inboxes.  I will try to see if there is some way to indicate whether a link has been modified in some way so that you know there has been an update.  Or if any of you know how to implement that by all means go for it.

    <li>Measure absorbance spectrum of Arabinose

  • Plate-test UT2, UT3, DH5a, UT13, I13522 (See below for protocol)

Andy:

  • Gel-extrated R0011 (2005) S/P (band: 2000 - correct)
  • Cannot gel-extract I13507 (2005) X/P because there was no more extraction column (bands: 2500-3000, 2000-2500, 750-1000 - correct)
  • Transformed R0011 (2005), I13522 (2006), I13504 (2005/2006)
  • Quantitated
    • Q3400 (2005) E/X (no band)
    • Q4400 (2005) E/X (band: 5000 - correct 120 ng/uL)
    • Q3400 (2006) E/X (band: 5000 - correct 24 ng/uL)
    • Q4400 (2006) E/X (band: 5000 - correct 120 ng/uL)
    • UT1 D E/S (band: 2500-3000 - correct 18 ng/uL)
    • UT1 E E/S (band: 2500-3000 - correct 12 ng/uL)
    • UT1 F E/S (band: 2500-3000 - correct 30 ng/uL)
  • o/n of UT3 x 5, UT2 x 1, and DH5a x 4 for temperature, arabinose, and plate testing

To-do List:

  • Ligate UT1 with Q3400 (2006), Q4400 (2005/2006)
  • Make o/n of I13522 (2006) for miniprep and plate-test, I13504 (2005/2006), I13507 (2005) for miniprep
  • Gel-extract I13507 (2005) X/P
  • Temperature, arabinose, and plate testing
  • Purchase gel-extraction kit, make Amp plates

Guidelines for Plate-test:

  1. On an Amp plate, make 4 sectors (500 uL?) with varying arabinose (0.02%, 0.2%, 2%, 20%) and making sure they don’t touch each other (otherwise diffusion will happen and they’ll be the same concentration), let the arabinose area dry.
  2. Take o/n of UT3-DH5a and take out 200 uL and add 800 uL of fresh LB and incubate for 1 hr.
  3. Spin down the cells at 3000 RPM for 5 min and remove 800 uL of supernatant. Resuspend cells with the remaining 200 uL and gently spread onto plate

Guidelines for Temperature-test:

  1. Put a constant amount of arabinose (either 0.02% or 0.2% - don’t want TOO much repression) in each dilution.
  2. Grow dilutions at 37C until the absorbance is ~0.6 using the GFP ABS program. Then take some tubes out and put 1 mL into an Eppendorf tube.
  3. Use the white filter caps and put them on each Eppendorf tube (to allow air in, but to protect against contamination)
  4. Set mixer to the equivalent to the shaker in the incubator (remember it’s a smaller tube, so there probably needs to be more force on it to get it to shake).
  5. Set temperature to 22C
  6. Check the absorbance after a couple of hours and prepare the samples when the absorbance matches the absorbance of the tubs in the incubator (these should be ready before the 22C ones are ready)
  7. Hopefully we’ll see a significant difference in fluorescence: cold should fluoresce less than hot.
