Swarm Assays

STARTED 2008-09-27


PURPOSE:
Test of the abbility of strains expressing the fusion receptor, to move against an attractant gradient.


STRAIN:
As autoinducer 2 producing attactant strain DH5α was used.
The fusion receptor plasmid was further cloned into HCB33 and UU1250 strains.


METHOD:
Petri-dishes were used es running chambers.
A petri-dish was filled with a media containig agar. Then the attractant was spotted on premarked positions or spotted as a line through the center of the petri-dish. After the gradient of the attractant has etablished the strains whioch should be attracted by the attractant where also set on premarked positions. The whole petri-dish was incubated at 37 °C and pictures were taken after 24, 48 and 72 hours. For a more detailed protocol visit the methods page.


A few pictures which have been taken during these experiments can be viewed under Projects.
