Ligation Summary

- Running total of number of ligations required for the assembly of testing constructs.


1) Promoter Testing (4-5 ligations)

2) PAH (3 ligations)

3) Cellulase (3 ligations)

4) Thermoinduction (7 ligations)

5) Restriction Enzymes (12 ligations)

6)Encapsulation (16 ligations)

Running total = 29-30

Promoter Testing

We aim to use a generic promoter testing system, however we are unsure of the exact promoters that we are using at this stage becuase of the timer situation.


At this present moment in time, we are estimating using 4-5 different promoters in our system. Since each will need to be characterised, 4-5 ligations will be required to faciliate the assembly of the testing constructs.


Testing Construct Assembly:

Input: POPs

Output: GFP

Parts Required: BBa_E0240, Each promoter to be characterised.

Module 1

Testing Construct Assembly

We must test both cellulase and PAH, both testing constructs can be made using a total of 6 ligation steps.

  • James Chappell 04:26, 4 August 2009 (EDT):I would join the RBS-Gx to the T first, think about the type of modules we want to submit to the registry. Think having a module that takes pops in and gives out G4 output is a good module to submit.

2) Restriction Enzymes

In total there will be 12 ligation steps.

We will test using a non-leaky pBAD promoter in order to utilise the GFP reporter cell death assay (see here).
An alternative to the GFP assay is to measure colony forming units.
