Flotation cell lysis

Nov 01, 2005 The method introduced by Simon , involving lysis of the cells at a low salt concentration, treatment with DNAse to reduce the viscosity of the solution, followed by low-speed centrifugation to collect the vesicles by flotation, is generally used in studies on gas vesicles in

    The 1,024-amino-acid acylated hemolysin of Escherichia coli subverts host cell functions and causes cell lysis. Both activities require insertion of the toxin into target mammalian cell membranes. To identify directly the principal toxin sequences dictating membrane binding and insertion, we assayed the lipid bilayer interaction of native protoxin, stably active toxin, and recombinant peptides
