* Looks successful - David Tze: ~200 colonies on the ligation plates, 1 colony on the neg. ctrl plate.

CONCLUSIONS
* Looks successful. 2197, 2132 bands are hard to resolve at the 2000 kb range.

  • Digests (Fermentas FD)
Reagent Rxn1 Rxn2-5 Expected bands:
1. hPCD(E/S) = 3200, 186*
2. PLflex_pUC57(E/X) = 2763*
3. PLflex4_pUC57(E/X) = 2930*
4. PLrigid_pUC57(E/X) = 2763*
5. PLrigid4_pUC57(E/X) = 2931*

  • Gel purification
    • Sigma GenElute Gel purification kit
    • Elute & back-elute w/ 25 μL elution sln.


  • Measure conc.'s

    • Readings are very odd, which is typical for the Sigma gel extraction products.
    • Will try my luck with these and use an arbitrary volume of 2.0 insert and 2.0 vector.
    • Good insert : vector ratio should not be difficult to achieve since insert is very short.


  • Ligations
    • 2:1 ratio calculation: 186 bp insert / ~2800 bp vector * 2 * 50 = 6.64 ng insert
  1. DT001_pUC57: hPCD(E/S)/186 + PLflex_pUC57(E/X)/2763
  2. DT002_pUC57: hPCD(E/S)/186 + PLflex4_pUC57(E/X)/2930
  3. DT003_pUC57: hPCD(E/S)/186 + PLrigid_pUC57(E/X)/2763
