  • ✓ Digest: confirm KAH105-108 (& /MV2) via E/P digests
  • ✓ Minipreps: KAH126-133/MV2 (2 ea); KAH123, 125 (6 ea)
  • ✓ Assemblies: KAH117-119; KAH135, 136

Digest check
> May have mixed up and mislabeled KAH105-108 (& /MV2). Sequencing results are out of order (see | 12/09/09). Could be cause of last failed transfection experiment.

Reagent Volume Expected:
MV2 = 4529
1. KAH105 = 2794
2. KAH105/MV2 = 2794
3. KAH106 = 2788
4. KAH106/MV2 = 2788
5. KAH107 = 2966
6. KAH107/MV2 = 2966
7. KAH108 = 2960
8. KAH108/MV2 = 2960 		K-stop testers, check 12/16/09

Results are consistent with the sequencing data: 1 = KAH108, 3 = KAH105, 5 = KAH106, 7 = KAH107
--> Correct labeling on the tubes
