1. Transform MLC2v and ANF plasmids into TOP10 cells.
+
-
2. Start vector double digest of pcDNA 3.1 + neo and pcDNA 3.1 + puro.
+

Transformations
+
-
5 microL of eluted plasmid to transform MLC2v and ANF plasmids each.
+
-
 
+
-
8/22/12 RN NKG LF (Exp 34)
+
-
 
+
-
Only one of the plates grew a colony from yesterday. ANF plate yielded no colonies. MLC2v plate yielded 1 colony.
+
-
 
+
-
Agenda for today:
+
-
1. Dilution plate the MLC2v colony from yesterday (33).
+
-
2. Transform ANF-eGFP plasmid and MLC2v-eCFP plasmid again into TOP10 bacteria through heat shock.
+
-
3. Work on wikipage and logo. Take pictures for wikipage and club.
+
-
 
+
-
Dilution plates
+
-
Logan dilution plated the MLC2v colony, and it is growing up in the warm room. This colony has also been placed in a conical tube (LB + kana) and is also growing up in warm room on shaker.
+
-
 
+
-
Transformations
+
-
The transformations of ANF and MLC2v plasmids are in the warm room, plated on amp and kana plates, respectively. We used 5 microL of each eluted plasmid, and all 250 microL was plated.
+
-
 
+
-
Assay
+
-
We ran an assay to determine the amount of eluted plasmid in the microfuge tubes. (The original amount eluted from the filter paper). This was accomplished via the Qubit fluorometer.
+
-
 
+
-
(Exp 35)
+
-
 
+
-
We spoke with Dr. Balza about our plates from yesterday and the lack of DNA in the eluted plasmid (hoping just a very small amount, not missing altogether). He suggested that we use 10 microL of eluted plasmid and 20 microL of TOP10 cells for each transformation. So we are doing another transformation today.
+
-
 
+
-
(2) MLC2v eluted plasmid 10 microL
+
-
TOP10 cells 20 microL
+
-
 
+
-
(2) ANF eluted plasmid 10 microL
+
-
TOP10 cells 20 microL
+
-
 
+
-
We are heat shocking them as the transformation method.
+
-
 
+
-
Agenda for tomorrow:
+
-
1. Safety questions and abstract
+
-
2. Check plated TOP10 cells
+
-
3. Miniprep MLC2v and glycerol stock
+
-
4. Restriction digest on MLC2v
+
-
5. Gel for pcDNA3.1 + neo, puro, and MLC2v.

8/26/12 RN NKG (Exp 40)
+
-

Double digest (39) gave ambiguous results. Looks like one enzyme did not work…we are redoing both enzymes separately for MLC2v. MLC2v 5 did not show anything on gel, so it is removed.

-
Using puro plasmid from 9/17/12 to run single digests (Pme1, EcoRI). If the enzymes are negatively interacting with one another as we suspect, the single digests followed by purification and the other  enzyme’s single digest will remedy this. Digest runs for 1 hour. Run in a gel to separate cut from uncut.
