  • Kevin Baldridge 17:30, 1 April 2013 (EDT):anabaena flos-aquae, that's an oorganism? It should be italicized if so
  • Kevin Baldridge 17:33, 1 April 2013 (EDT):Your chart of the ELISA results for TNP needs some explanation. What is the difference between the four TNP samples? Citation for the chart?
  • Kevin Baldridge 17:35, 1 April 2013 (EDT):Any evidence for the gas vesicle display of antigens being any more or less effective than traditional attenuated/dead pathogen approaches to immunization?
    • Benjamin Gilman 16:31, 3 April 2013 (EDT): I was also wondering what the reasoning behind attaching an antigen to a gas vesicle was and the page should explain this. Is it to prevent degradation or excretion of the antigen? If so, how long do these gas vesicles remain in the blood and could they present other problems (like aggregation)?
  • Gabriel Wu 19:20, 3 April 2013 (EDT): What's known about the proteins that make up gas vesicles? Are there many different kinds of subunits? How do they assemble?
  • Aurko Dasgupta 00:18, 5 April 2013 (EDT): The graph on immunization status feels a little dishonest. By counting every mouse as a separate bar, instead of grouping them together and using error bars, their presenting their study as more thorough that it actually was. Also, did the 4th mouse die between the 2nd booster and the 8th month?
  • Max E. Rubinson 00:11, 5 April 2013 (EDT): How are gas vesicles formed in response to low light conditions in cyanobacteria? They must somehow be able to upregulate gene expression in response to low light.
    • Max E. Rubinson 00:34, 5 April 2013 (EDT): I was wondering if maybe the expression of gas vesicles in flos-aquae remains constant, and buyoancy is attenuated solely by an increase in carbohydrate concentration due to increased rates of photosynthesis at the surface, but in the 1994 review from Walsby, there is a section discussing the fact that increased gas vesicle content in flos-aquae and other species correlate with decreased photon irradiance.
