Webliposomes a pH of 7-8 is obtained by adding sodium carbonate buffer. Dissolved doxorubicin HCl is added and the membrane-permeable neutral form (in excess at pH 7.5) crosses the liposome bilayer into the aqueous core where it is protonated and, as such, forms a complex with citric acid. The WebNov 28, 2013 · Therefore a citric acid based buffer (pH 4.4) was evaluated for aggregate formation after electroporation. Following electroporation of this buffer in the presence of Cy5-siRNA, no fluorescent aggregates could be detected and only minute amounts of particles could be measured via NTA ( Fig. 3 A, right panel and 3 B, respectively).
