Preliminary data

Using pBEST-OR2-OR1-Pr-UTR1-deGFP-T500, a plasmid enhanced for GFP expression, the biomolecular breadboard is able to express mass at equal concentrations to comparable bacteriophage in-vitro systems (J. Shin and V. Noireaux, 2010).

Expression of plasmids can be optimized by concentration.

  • Raw data file: plasmid_deGFP-070812.xls (Excel spreadsheet)
  • Information about protocol on "Outline" sheet; plotted data is on the sheet "plotted-data"
