The antibacterial action of modified AG30. The antibacterial action of modified AG30 is evaluated to (A) P. aeruginosa (ATCC27853), (B) Candida (ATCC90028), (C) S. aureus (ATCC29213) and (D) MRSA. MIC assays were performed in the concentration range of 1.25–40 mg/ml of modified AG30, LL37 against P. aeruginosa and 3.1–100 mg/ml against Candida, S. aureus and MRSA. MIC was defined as the lowest peptide concentration, which prevented visible bacterial growth in the medium. Lower panel shows representative pictures of MIC assays with treatment of several peptides.
