Chris

Purification of AtCRE
  • used PCR clean up kit to purify AtCRE sample
    • Tranformation of Competent Cells
  • followed transformation of competent cells protocol to insert AtCRE plasmid into preprepared competent E. coli cells.
  • allowed cells to incubate overnight at 37 C

    • Matt

    Ligation
  • As suggested by Dan the ligation was spiked with 1 ul ATP.
  • I then performed a PCR cleanup of the Ligation product in order to purify it for transformation into competent cells.
    • Transformation
  • A transformation was performed on PTP2 ligation product - I then left the streaked plates to incubate for tomorrow.
  • A glycerol stock was finally made of the BY4642 yeast strain int. DQ232597.

    • Dan

    Gel of construct 1 after ligation
  • Gel was unsucessful, the wrong primers were used for PCR amplification.
  • Ligation seemed to work very efficiently, digesting in 50 uL with the new ClaI enzyme is working very well.
    • Digestions
  • Three digestions were performed 1+T, 1+T (higher concentration of vector and insert), and just the vector
    • Ligations
  • Three above plasmids were ligated overnight

    • Tammy

    Plasmid DNA Isolation
  • XL10 Competent E.Coli cells transformed with pDR197::AtCKX2 were lysed and plasmid DNA was isolated using the Sigma-Aldrich kit.
  • Average DNA concentration approximately 80 ng/μL


    • Digestion of isolated pDR197::AtCKX2
