LB-medium is badly needed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

GVP Cluster

EM pictures

TODO Today we will try to get some Electon microscopy pictures of the gas vesicle producing bacteria from the ON cultures.

Orinigal pNL29 iptg-GVP and the biobricks ars-GVP and

TODO Choose colonies from plates for growth of E.coli TOP10 with GVP behind LAC/pBAD (+RBS) promoter in pSB1AC3
TODO Make glycerol stocks of pBad/araC, pBad/araC+RBS+GVP, and pLacI+RBS+GVP (both in pSB1A2 and pSB1AC3 plasmid)
TODO Test control of bouyancy in Saline solution (grow plates with GVP constructs)
TODO Order synthetic DNA for GVP
TODO Order primer for PstI site removal
TODO Test promoter strenght compared to BBa_J23101 promoter (Sven)
TODO Enter sequences of constructs to Sandbox


Colonies on Plates

Name Plasmid Used Antibiotics on Plasmid No. of Colonies Date
pLacI-GVP http://partsregistry.org/Part:pSB1A2 pSB1A2] Ampicillin 26 3/9
pLacI-GVP (concentrated) http://partsregistry.org/Part:pSB1A2 pSB1A2] Ampicillin ~100 3/9
pBad/araC-GVP http://partsregistry.org/Part:pSB1A2 pSB1A2] Ampicillin 1 3/9
pBad/araC-GVP (concentrated) http://partsregistry.org/Part:pSB1A2 pSB1A2] Ampicillin ~40 3/9
Negative Control MQ None 0 3/9
Positive Control J61002-J23101 Ampicillin ~2000 3/9


→ The plates showed normal colony growth.


O.n. precultures

→ All twelve o.n. precultures showed bacterial growth, and could be used to isolate plasmid. The first four are registry vector pSB2K3 with RFP as reporter (plate 1, 7C) which were transformed on tuesday. The isolated plasmid is used to house all GVP constructs to combine with the vector pSB1AC3 with transporter and accumulation genes.
→ The next eight tubes contain our own designed biobricks and isolated plasmid will be sent to the registry on friday!

Plasmid Purification

Plasmid isolation was performed on the cultures of E.coli TOP10 containing the above mentioned plasmids with the "Sygma-Aldrich™ GenElute™ Plasmid Miniprep Kit".

  • From each tube 4mL of culture was collected in a 2.0mL cup, and the cells were pelleted by centrifugation for 1 min. at max. speed and the supernatant discarded.
  • Plasmids were eluted with 30μL MQ and stored in the fridge

Restriction for Assembly

The vectors pSB1A2 containing the pLacI/GVP and pBad/araC/GVP composite parts were cut with PstI and EcoRI to create correct ends for insert into pSB1AC3, which was also cut with EcoRI and PstI.
