Centre for Thrombosis and Vascular Research, School of Pathology, University of New South Wales, Sydney, NSW 2052, Australia In the above-mentioned article, an error was made in the estimation of the endothelial cell surface concentration of protein disul¢de isomerase. A concentration of 30 nanomolar was indicated but this should read 15 micromolar. The error does not change the results or conclusions of the article but can be misleading.
