Membrane permeabilisation. Cell permeabilisation is measured by the internalisation of SAv-Cy5 for (a) 4 T1 cells and (b) E. coli. (Left) Histograms showing Cy5+ maximum fluorescence intensity (n = \( \overline{\mathrm{x}} \) 6). (Right) Box plot showing median fluorescence intensity. Deviation (%) from impermeabilised shown above each box in blue/red and p-values are shown in black. In all cases n = 6
