Cytoplasmic membrane variation of E. coli UB1005 treated by peptide and ME26.

The dye (diSC3-5) release intensity was monitored at an excitation wavelength of 622 nm and an emission wavelength of 670 nm. The concentrations of the peptides were their 2× MIC (A, R-FV-I16; B, ME26), and 1× MIC (C, R-FV-I16; D, ME26).
