Minipreparation and Confirmation of PTP2/PSSA42 samples

  • Control (tip only in LB+Amp) was clear
  • Followed miniprep protocol included in kit
  • Spilled one tube; concentration expected to be zero. Also, did not mix neutralisation solution as outlined in the protocol.
  • Measure absorbance of isolated DNA: all samples very low and poor purity.
  • Digested aliquots of all samples with PstI despite low concentrations. Expected bands (1246, 699, 5685) appeared on a 1% gel; however were faint and inconclusive.
  • While the gel was running, performed another miniprep of the same ten samples, following protocol exactly in order to increase DNA concentrations.
  • Continuation of Ligation Optimisation

  • Ran all products on a 1% gel for 40 minutes at 80V.
  • All ligations appeared exactly the same on the gel; future ligation protocol will be shortened from overnight to a minimum of six minutes.
