CDy11
CDy11 is a fluorescent probe and amyloid-binding dye (λex=590 nm; λem=612 nm), with a Ka of 29 μM for Pseudomonas aeruginosa Fap. CDy11 specifically recognizes amyloid fibrils in bacterial biofilms and exhibits significantly enhanced fluorescence upon binding to the target. CDy11 shows no staining effect on amyloid-deficient mutant strains, planktonic cells or protein monomers. CDy11 supports in vivo imaging of Pseudomonas aeruginosa biofilms in mouse implant and corneal infection models. CDy11 is widely used in studies of Staphylococcus aureus biofilm infections, dental caries, and Pseudomonas aeruginosa-associated implant and corneal infections.

Biological Activity
CDy11 (100 μM; 45 minutes) specifically detects amyloid fibril matrix components of Staphylococcus aureus GFP-SH1000 biofilm-coated silica microbeads, producing a strong red fluorescent signal that co-localizes with bacterial green fluorescence[1].
CDy11 detects Pseudomonas aeruginosa biofilms with a limit of 8×108 CFU/mL[2].
CDy11 (1 μM; 1 h) co-localizes with Fap-specific antibody staining in Pseudomonas aeruginosa PAO1 biofilms, confirming specific binding to Fap amyloid[2].
