Abstract
This paper presents a novel evaluation method for determining platelet/material interaction at the transmembrane level by incorporation of a Ca-sensitive fluorophore (Fura-2) into platelets. The transmembrane stimulation of platelets which are eluted from commercially available artificial dialyzers was quantitatively measured as the elevation of intracellular free calcium ion concentration. This method clearly differentiated platelet response to hydrophilic (ethylene vinyl alcohol copolymer and cellulose) vs. hydrophobic (polyacrylonitrile and cellulose acetate) membranes, and offers a versatile means to understanding platelet/material interaction.Keywords
