Trypsin: An anti-human cationic trypsin antibody was used at 1:1000 (Biodesign, Kennebunk, ME).
4B) shifted from approximately -24 mV in the initial state to about -4 mV in the activated state, consistent with the activation of a non-selective cationic conductance permeable to both Na +and K +. Similar results were observed for other SNP-activated oocytes (n = 5), as well as for AQP1-expressing oocytes activated by prior incubation in 10 mM 8Br-cGMP (as described in [ 11 ] ). In AQP1-expressing oocytes, the conductance induced by 8Br-cGMP in control Na +saline did not change significantly [(+) 11.
Resistance to polymyxin B is also imparted by the absence or masking of critical binding sites required for polycation-mediated permeabilization of the outer membrane [ 54 ] . Thus, attachment of polymyxin B to Yersinia enterocolitica is reduced by steric hindrance generated by the size and/or branched shape of the outer core region of its LPS macromolecule [ 55 ] . Additionally, resistance to cationic peptides can be due to cytoplasmic clearance of the antimicrobial peptide by an efflux pump; e.g., Yersinia resistance to polymyxin B caused by the RosA/RosB efflux pump/potassium antiporter [ 56 ] and Neisseria gonorrhoeae resistance to protegrin PG-1 via an energy-dependent efflux system termed mtr [ 57 ] .
Synthetic vectors include cationic polymers such as polyethyleneimine (PEI) and polylysine, as well as cationic lipids such as Lipofectamine [ 2] and negatively charged liposomes [ 3].
For example, sensitivity to the antibacterial lipopeptide polymyxin B is affected by the PmrA-PmrB regulon, which mediates substitution of 4-aminoarabinose on the 4´ phosphate of lipid A [ 52 53 ] . By reducing the negative charge of lipid A, this modification decreases its electrostatic interaction with cationic peptides.
