Lab work

Characterization of Anderson RBS sequences

E.coli Top10 strains containing the following composite BioBricks in pSB1A2 had been obtained:

BioBrick Composed of:
[http://partsregistry.org/Part:BBa_K398500 K398500] J23100 + J61100 + I13401
[http://partsregistry.org/Part:BBa_K398501 K398501] J23100 + J61101 + I13401

To prepare for the fluorescence assay measurements the strains were grown in 3 mL LB medium containing 100 μg/mL AMP as well as in M9 minimal medium containing 0.4% glucose and 100 μg/mL AMP.

High copy number RBS characterizations are rarely indicative of RiPS in system operation plasmids, thus we are planning to also measure the fluorescence assays with the BioBricks on pSB3C5. In order to obtain sufficient BioBrick DNA the strains were grown in 250 mL LB with 100 μg/mL Ampicillin, awaiting plasmid isolation and plasmid swapping.

Emulsifier

The bricks for emulsifier production were assembled. The stock plasmids containing AlnA, OprG, R0011 and B0032 were digested and ligated into plasmid pSB1T3.

Digested were performed according to the digestion protocol:

# Sample Enzyme 1 Enzyme 2 Buffer BSA Needed fragment
1 1.0 μg AlnA EcoRI SpeI 2 (BioLabs) ✓ ‘E–AlnA–S’
2 1.0 μg OprG EcoRI SpeI 2 (BioLabs) ✓ ‘E–OprG–S’
3 1.0 μg R0011 EcoRI SpeI 2 (BioLabs) ✓ ‘E–R0011–S’
4 1.0 μg B0032 XbaI PstI 2 (BioLabs) ✓ ‘X–B0032–P’
5 1.0 μg B0015 XbaI PstI 2 (BioLabs) ✓ ‘X–B0015–P’
6 1.0 μg pSB1T3 EcoRI PstI 2 (BioLabs) ✓ ‘E–linear pSB1T3–P’

The digestion products were ligated overnight:

# BioBrick Fragment 1 Fragment 2 Recipient vector
1 K398202 μL ‘E–R0011–S’ μL ‘X–B0032–P’ μL ‘E–linear pSB1T3–P’
2 K398203 μL ‘E–AlnA–S’ μL ‘X–B0015–P’ μL ‘E–linear pSB1T3–P’
3 K398204 μL ‘E–OprG–S’ μL ‘X–B0015–P’ μL ‘E–linear pSB1T3–P’
4 negative control - - μL ‘E–linear pSB1T3–P’
