Figure 1From: Comparative analyses of proteins from Haemophilus influenzae biofilm and planktonic populations using metabolic labeling and mass spectrometry Schematic illustrations of the continuous-flow growth chambers used to grow the (A) biofilm and (B) planktonic organisms. The biofilm (“B”) organisms were grown with “heavy” 13C6-Isoleucine and the planktonic organisms (“P”) were grown with unlabeled or “light” isoleucine. The inserted micrograph in panel (A) is a scanning electron microscopy image showing a typical biofilm from these growth chambers.Back to article page
