Determination of pore size of the cell wall of Chara corallina has been made by using the polyethylene glycol (PEG) series as the hydrophilic probing molecules. In these experiments, the polydispersity of commercial preparation of PEGs was allowed fo

Using hydrophilic non-electrolytes, we determined the effective diameter of calcium channels from the Characeae alga Nitellopsis, reconstituted in a planar lipid membrane. It is suggested that a "single" reconstituted channel is a cluster consisting

Radii of ion channels formed in the lipid bilayer by 4 homologs of the alamethicin-like antibiotic, chrysospermin, were determined using hydrophilic nonelectrolytes. It is shown that the replacement of isovaline amino acid at position 15 of the polyp

The effects of nonelectrolytes on conductivity and viscosity of KCl solutions as well as on ion channel conductance were studied. Mobility of ions in solutions were found to solely depend on percent concentration (w/w) of the nonelectrolytes added an

Polyethylene glycols (PEG) with molecular weight less than or equal to 3000 were shown to effectively protect human erythrocytes from osmotic lysis induced by alpha-staphylotoxin (ST). PEG with MW less than 3000 do not change the conductivity of ion
