Differential scanning calorimetry studies showed a decrease in phase transition temperature ( T ( m ) ) upon an increase in the percentage of doping of TamNHMe and CA - Tam ( 3 ) - Am , whereas LA - Tam ( 1 ) - Am and DCA - Tam ( 2 ) - Am do not cause a major change in the phase transition temperature ( T ( m ) ) of DPPC liposomes .
 TamNHMe, CA - Tam, LA - Tam, DCA - Tam, DPPC
