For our system we needed three plasmids with different origins of replication and antibiotic resistances. We decided to take low copy plasmids. We also decided to use the following plasmids, which we wanted to modify so that they would become compatible to the Biobrick Library multiple cloning site:

It is important to insert parts responsible for the production of fluorescent proteins in low copy plasmids, as they are potentially harmful for the cell. Unfortunately, working with low copy plasmids makes the procedure more demanding in the lab.

=== Procedure ===
 
-
The standard BioBrick assembly will be used to put the parts in the plasmids. Detailed information on how the BioBrick part fabrication works can be found  [http://openwetware.org/wiki/Synthetic_Biology:BioBricks/Part_fabrication here]. For a shorter explanation of how to assemble 2 parts together check [http://partsregistry.org/Assembly:Standard_assembly here]. [[Image:Assembly _process.png|thumb|300px|DNA assembly process ([3])]] Note that the composite part is constructed from the end to the beginning, i.e. each new part is inserted ''before'' the existing one. Composite parts made of parts '''a''' and '''b''' are denoted '''a.b'''.

Introduction

On this page, you can find information about how educatETH E.coli was implemented in the lab. More specifically, you will find information on the plasmid strains we used, the modifications we did to them in order to be compatible with the Biobrick library and our cloning plan. Moreover, you can find here an (unfortunately not complete) electronic copy of our lab notebook. If you are here because you are interested in implementing educatETH E.coli in your lab, then our System Implementation and the System Parts pages may be of help to you!

For all our cloning procedures we used standard protocols according to SAMBROOK and RUSSELL Molecular Cloning: A Laboratory Manual [1].

Strains

We used the following E. coli strains:


E. coli Top10 (Invitrogen):

  • You can find this strain at BBa_V1009
  • This strain has a streptomycin resistance
  • Genotype: F’ {tetR}, mcrA, Δ(mrr-hsdRMS-mcrBC), φ80 lacZ ΔM15, ΔlacX74, deoR, recA1, araD139 Δ(ara-leu)7679, galU, galK, λ-, rpsL,endA1, nupG

E. coli JM101:

  • You can find this strain at BBa_I739301
  • We call them Jimmys

Plasmids

For our system we needed three plasmids with different origins of replication and antibiotic resistances. We decided to take low copy plasmids. We also decided to use the following plasmids, which we wanted to modify so that they would become compatible to the Biobrick Library multiple cloning site:


Basic plasmids

Plasmid Resistances Copy number Origin Map
pBR322 [2,3] Ampicillin, Tetracyline 15-20 [4] pMB1
pBR322 Map
pCK01 [5] Chloramphenicol 5-12 [4] pSC101
pCK01 Map
pACYC177 [6,7] Ampicillin, Kanamycin 10-12 [4] p15A
pACYC177 Map


Changes to the plasmids

In order to get the Biobrick multiple cloning site into the plasmids, we had to make several changes to the plasmids:


Plasmid Changes New name New resistance New Map
BBa_I739201
  • Site directed mutagenesis: Changed the GCA codon of the PstI site of the bla gene into GTA
  • Cloned in linker oligos (EcoRI/BamHI)

Cloning plan

Parts assignment into plasmids

The plan was to put the following parts into the three plasmids (for the detailed cloning procedure see below):

plasmid resistance copy type contents comments
BBa_I739201 ampicillin low BBa_I739001(TetR) , BBa_I739002(LacI) , BBa_I739003(LuxR) constitutive subsystem
BBa_I739202 chloramphenicol low BBa_I739004(P22 cII) , BBa_E0430(EYFP) , BBa_I739008(cI) , BBa_I739009(ECFP) reporting subsystem
BBa_I739204 kanamycin low BBa_I739006(cI) , BBa_I739007(P22 cII) , BBa_I739010(RFP) , BBa_I739011(GFP) learning subsystem, reporting subsystem

It is important to insert parts responsible for the production of fluorescent proteins in low copy plasmids, as they are potentially harmful for the cell. Unfortunately, working with low copy plasmids makes the procedure more demanding in the lab.


Cloning procedure

The standard BioBrick assembly will be used to put the parts in the plasmids. Detailed information on how the BioBrick part fabrication works can be found here. For a shorter explanation of how to assemble 2 parts together check here.
DNA assembly process [8]
Note that the composite part is constructed from the end to the beginning, i.e. each new part is inserted before the existing one. Composite parts made of parts a and b are denoted a.b.
