FIG. 3.
Effects of various media on the activity of LL-37. Mid-logarithmic-phase E. coli ML-35p, approximately 2 × 106 CFU/ml, was incubated for 2 h with various concentrations of LL-37 in three different media: 10 mM sodium phosphate buffer plus 100 mM NaCl and dilute Trypticase soy broth (•), standard (std) MHB (■), and refined (ref) MHB (▵).
