TY - EDBOOK AB - The functional assembly of FITC-Na,K-ATPase membrane fragments on a surface-modified Ta2O5 waveguide allows to investigate the directed binding of ligands by surface-confined fluorescence studies. The results allow to draw conclusions about the sidedness of interactions. The fluorescence intensity decrease observed upon the selective binding of K+ is attributed to its coordination to a site accessible from the former intracellular membrane side.
