Cell wall-binding (CWB) domain of Staphylococcus aureus autolysin is used as an affinity reagent for bacteria.

Fluorescence image of CWB-GFP (green-fluorescent protein) fusion that binds to gram-positive bacteria is shown in this cover page. Growing bacteria are mixed with purified CWB-GFP and then observed with a fluorescence microscope. S. aureus, Corynebacterium glutamicum, Bacillus subtilis, Escherichia coli, Agrobacterium tumefaciens, and Pseudomonas aeruginosa were used (from top left to bottom right). Phase-contrast (left) and GFP (right) images are shown. CWB-GFP bound to a wide range of gram-positive bacteria, but not to most gram-negative bacteria.
