Cell-free circuit breadboard
The following protocols are available for the cell-free circuit breadboard:
- Reaction Preparation - Cell-free expression of circuits from linear or plasmid DNA
- TXTL template, v2.3 - TXTL spreadsheet for designing experiments
Cost estimate
The cell-free circuit breadboard costs approximately 2.64 cents per uL, or 31.7 cents per 12 uL reaction. The cost distribution is shown in the table below.
