examined using developed electrochemical cell with two
compartments separated by a phospholipid membrane
created in pores of polycarbonate support. At first cell
penetrating peptides (transportan 10 and mastoparan X)
were used to allow the transfer of phytochelatin PC2. The
results demonstrated that transportan 10 is several times
more efficient than mastoparan X for transferring of phytochelatin
across model membrane. Voltammetry with
hanging mercury drop electrode or with solid amalgam
electrodes was applied for detection of transported species.
For determination of PC2, hanging mercury drop electrode
and mercury meniscus-modified silver solid amalgam
electrode were suitable. Modified model phospholipid
membrane was prepared with parts of protoplasts from
barley roots or leaves, and transport of phytochelatin PC2
has been confirmed. Electrochemical impedance spectroscopy
was utilized to monitor formation, stability, and
qualitatively the transporting process across the supported
phospholipid membranes.Pracoviště Ústav fyzikální chemie J.Heyrovského Kontakt Michaela Knapová, michaela.knapova@jh-inst.cas.cz, Tel.: 266 053 196 Rok sběru 2017
