Study of the influence of ascorbyl palmitate and amiodarone in the stability of unilamellar liposomes.

abstract：:TGN38 is a heavily glycosylated, type I integral membrane protein which is predominantly localized to the trans Golgi network (TGN), but which constitutively traffics between the TGN and the cell surface. The trafficking of TGN38 has been extensively studied in non-polarized cells, and a short, tyrosine-based, peptide...
