Timeline



Week 26

- Preparing for take-off


  • Inventory of the lab supplies
  • Pouring LB Agar plates
  • Amplification of the pET-Duet-1 vector
  • Assessment of the safety requirements
  • Preparing stocks for antibiotics, glycerol, LB & MilliQ


Week 27

- The Clone Wars


Gibson Assembly:
  • Linearizing pET-Duet-1 for Gibson Assembly
  • Our first Gibson Assembly!

Traditional cloning:
  • Amplification of the pET-Duet-1 vector
  • Nde1 & Kpn1 digestion of the pET-Duet-1 vector (MCS-2) for traditional cloning


Week 28

- Et tu, pET-Duet?


Gibson Assembly:
  • Linearizing pET-Duet-1 for Gibson Assembly and debugging
  • Digestion of the template using DpnI
  • Running a gel to check whether the linearization was successful
  • Gibson Assembly for MCS1
  • Transformation and amplification of the plasmid

Traditional cloning:
  • Amplification of the inserts
  • Xbal & Pstl digestion of the pET-Duet-1 vector (MCS-1)
  • Xba1 & Pst1 digestion of the inserts (MCS-1)
  • Nde1 & Kpn1 digestion of the inserts (MCS-2)
  • Ligation
  • Transformation in NB
  • Colony PCR & gel electrophorese: The inserts are succesfully ligated
  • Culturing of the colonies with the correct plasmid
  • Making a glycerol stock & sending the DNA for sequencing


Week 29

- Hopeful results


Gibson Assembly:
  • Plasmid isolation, followed by sequencing of the insert on MCS1
  • Linearization of the vector on MCS2
  • Gibson Assembly of the second MCS
  • Colony PCR of MCS2, showing promising results!
  • Culturing and preparing for protein expression

Protein expression:
  • Double transformation of pET-Duet-1 (MCS1) and pEVOL in BL21.
  • Culturing & making a glycerol stock

Traditional cloning:
The sequencing results are positive, everything is built in correctly.

Week 30

- The moment of truth


Gibson Assembly:
  • Plasmid Isolation, followed by sequencing of the insert on MCS2

Protein expression of the plasmids containing MCS-1:
  • Culturing and protein expression of pET-Duet-1 (MCS-1)
  • Labelling the bacteria with DBCO-PEG4-Tamra
  • FACS results don't show the click reaction...

Double transformation & protein expression of the plasmids containing MCS-1 & MCS-2:
  • Double transformation, culturing and protein expression of pET-Duet-1 (MCS-1 & MCS-2)
  • The click reaction occured according to FACS results
