Having decided on our biobrick design, our first task was to aquire the necessary parts and construct our first biobrick.

BBa_I13522 was taken from well 8A kitplate 2 of the 2010 distribution BBa_K216005 was requested from the parts registry

Construction of the biobrick can be broadly broken down into

  • Generating larger quantities of both our component biobricks
  • Digesting each of these biobricks
  • Ligating together the desired parts to create a new biobrick
  • Generating larger quantities of this biobrick, checking and sequencing


Generating large quantities of DNA:

  • Whilst waiting for DNA from the parts registry we tried to obtain large amounts of the constitutive GFP biobrick
  • We initially tried transforming MG1655s with DNA from the kit plate but were unsuccessful. Suspected the problem was down to cells not being competent enough and insufficient DNA in kit plate.
  • Thus we tried transforming two further strains; XL1 Blues and commercial NovaBlues (see table for details)
XL1-blue positive control 100μL cells + 2μL known plasmid solution
XL1-blue negative control 100μL cells (untransformed)
XL1-blue + 2009 biobrick 100μL cells + 5μL 2009 biobrick
XL1-blue + 2010 biobrick 100μL cells + 5μL 2010 biobrick
Nova blue + 2009 biobrick 100μL cells + 5μL 2009 biobrick
Nova blue + 2010 biobrick 100μL cells + 5μL 2010 biobrick
  • Only the commercial cells were successful and provided us with colonies
  • Colonies then selected and used to grow overnights - using a wire loop to inoculate 5mL of LB medium (5μL of Ampicillin also added)
  • These overnights were then miniprepped using QIAGEN kit to obtain 50μL of concentrated DNA
