Erratum for vol. 93, p. 2552

In the article by Thorelli, Kaufman, and Dahlback, entitled “Cleavage of Factor V at Arg 506 by Activated Protein C and the Expression of Anticoagulant Activity of Factor V,” which appears in the current issue on pages 2552 through 2558, a correction should be noted. This paper should be classified under the “Hemostasis, Thrombosis, and Vascular Biology” section and not the “Hematopoiesis” section as listed.
