  • ✓ Cultures/minipreps: KAH235(2), retransformations DPRE, MV1
  • ✓ Assemblies: PCR inserts for pSB31 cloning



Minipreps
> Check 1-3 with E/S digests (DPRE has PstI sites)
> Check 4 w/ E/P

Reagent Volume Expected:
1,2. KAH235 (E/S) = 2787
3. DPRE (E/P) = 1740
4. MV1 (E/S) = 4102, 1326
Miniprep digests 8/07/11
15 μL/lane; 1% agarose
DNA(plasmid) 2.0 μL
10X buffer 1.5
EcoRI 1.0
SpeI 1.0
dH2O 9.5
  15 μL --> 37°C/ ~15 min.

--> Mixed up minipreps MV1 and DPRE (3 is MV1 and 4 is DPRE KAH014)
3. MV1 (E/S) = 4742, 686
4. DPRE (E/P) = 3200, 1740 (forgot that I had done s.d. mutagenesis on DPRE to make KAH014, 4/02/10)
