to provide insight into charge effects on transendothelial passage , the permeability values of small inorganic cations ( labeled sodium and rubidium , and stable potassium ) and anions ( labeled chloride , iodide , sulfate , and ferrocyanide ) were compared to those expected for neutral solutes with approximately matched diffusion coefficients , and that of a neutral dextran fraction was compared to that of a negatively charged dextran sulfate with a similar diffusion coefficient .
