Emilysimso Week 11

Experimental Design

• Control: wild-type S. oneidensis MR-1
• Treatment: used 2,2'-dipyridyl diluted to 80, 160, 240, and 320 micro-molar concentrations
• Biological treatments - all of the studies were done in triplicates
  • Three samples per treatment
• Number of chips: 12 (3 samples x 4 treatments = 12)
• Dye swaps - unable to find evidence of this in the paper
