Somewhere in the beginning of July, we started our wetwork. We started the summer off working in smaller teams: we had a team working on Gibson Assembly, a team responsible for Traditional Cloning and a team working on Interlab. In this way, we could fit tons of wetwork within the few weeks of the summer holidays. Below, we hope to give a short overview of how we started off and which experiments we carried out in which weeks.

Timeline



Somewhere in the beginning of July, we started our wetwork. We started the summer off working in smaller teams: we had a team working on Gibson Assembly, a team responsible for Traditional Cloning and a team working on Interlab. In this way, we could fit tons of wetwork within the few weeks of the summer holidays. Below, we hope to give a short overview of how we started off and which experiments we carried out in which weeks.

See the black timeline below for a global impression of the major experiments carried out by the teams working with Gibson Assembly and Traditional cloning. These experiments brougth us were we are today and results can be seen here.



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 MCS-1 of pET-Duet-1 for Gibson Assembly
  • Digestion of the template using DpnI
  • Running a gel to check whether the linearization was successful
  • Our first Gibson Assembly!
  • Plasmid amplification into NEB 5-alpha

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 MCS-1 of pET-Duet-1 for Gibson Assembly and debugging: sequencing results came back disastrous. It seemed as if pETDuet-1 had turned on us. In the end, however, it turned out that we had used the wrong primers. Always use the right primers, folks!
  • Digestion of the template using DpnI
  • Running a gel to check whether the linearization was successful
  • Gibson Assembly for MCS-1
  • Plasmid amplification into NEB 5-alpha

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

Week 30

- The moment of truth

Gibson Assembly:
  • Plasmid isolation, followed by sequencing of the insert on MCS-2

Protein expression of the plasmids containing MCS-1:
  • Culturing and protein expression of MCS-1 containing pET-Duet-1 vector
