| - | Made Mini-preps of B0015 (2005) – need to test tomorrow – and made o/n of B0015 (2005) for a freezer stock. B0015 (2006) didn’t seem to grow very well so let it grow for another day and mini-prep tomorrow.

| |
| - | <li>mini-prep B0015 (2006) – if cells have grown
| |
| - | <li>mini-prep all the I0500 + J06801 vials. Label them I+J
| |
| - | <li>test the mini-preps for correct lengths (I+J will have a plasmid length of pSB2K3 and a part
| |
| - | length of 1210 + 1371 = 2581 bp long)
| |
| - | <li>if test is good, proceed to ligation with E0240 (2005) and I13507 (2005). – NOTE: need to
| |
| - | digest the plasmid (E0240 and I13507) with EcoRI and XbaI and to digest the insert (I+J) with
| |
| - | EcoRI and SpeI – this is a pre-insertion.

| - | <li>Once ligation is complete, do an initial check to see if ligation was successful, if so,
| |
| - | transform cells with the new parts I+J+E and I+J+I.

| - | Made an o/n growth of B0015 (2005/2006) to have miniprepped and to make freezer stock
| |
| - |
| |
| - | 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)

| - | <ul>
| |
| - | <li>miniprep B0015 (2005/6) and I0500 (2005)

| - |
| |
| - | Double digested parts B0015 (2005), C0056 (2005) and I13507 (2005) again with EcoRI and PstI with Buffer EcoRI. To ligate the parts, I0500 (2005) will be the host and J06801 (2006) will be the insert. The new part will then be then inserted into the E0240 (2005) host. Therefore, I0500 will be cut with SpeI/PstI, J06801 will be cut with XbaI/PstI, and E0240 will be cut with EcoRI/XbaI.

| - | We started the mini-prep procedure for B0015 (2005) and I13507 (2005) by preparing an o/n growth of cells. We then prepared freezer stock of J06801 (2006), B0034 (2005), C0056 (2005), E0240 (2005), I0500 (2005), I12006 (2005).
| |
| - |
| |
| - | 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.
| |
| - |
| |
| - | To-Do List:
| |
| - | <ul>
| |
| - | <li>Repeat ligation attempt using I0500 (2005) and maybe continue with E0240 (2005)
| |
| - | <li>If plasmids are compatible, we can ligate I12006 (2005) and E0240 (2004) and co-transform
| |
| - | with a plasmid that expresses cI
| |
| - | <li>Transform B0031 (2005) to make a freezer stock after 2 days.
| |
| - | <li>Complete MP procedure for B0015 (2005), I13507 (2005)

| - | 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.

| |
| - | 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.

| - | 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.

| - | Hey team,
| |
| - |
| |
| - | 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.
| |
| - |
| |
| - | 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.

| |
| - | 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.
