Transport of Charged and Uncharged Species across Models of Biological Membranes

2008-2012

No. IAA400400806, Grant Agency of the Academy of Sciences of the Czech Republic

Abstract:
The project is aimed at the preparation and characterization of phospholipid bilayers at stabilized phase boundaries enabling studies of transfer of charged and uncharged species between the two phases.The best way for investigation of inorganic ion transfer is provided by using mercury as one of the phases,in view of the huge volume of the relevant electrochemical data available,whereas the transfer of more complex species is better studied in the system of an organic and an aqueous phase stabilized by agar gel.The results contribute to the understanding of ion transport across real membranes. Polypeptides and peptides capable forming ionic channels and enabling transport of various ions and molecules across the membranes, will be incorporated into the model membranes.The possibilities of transport of selected compounds across the model membrane will be investigated using cell permeable peptides as well. The investigation is primarily based on
electrochem. methods (e.g.,CV,IS,conductom).
