eight anionic buffers with relatively high ionic strength ( e.g. , phosphate and diethylmalonic acid ( dma ] yielded ghosts requiring atp for shape change , while two cationic buffers ( bistris and imidazole ) and ten synthetic zwitterionic buffers ( e.g. , tricine and hepes ) with lower ionic strength produced ghosts that smoothed spontaneously at 30 degrees c .
