Leading experimentalists describe in detail their proven, cutting-edge methods for research on hemostasis and thrombosis, as well as their diagnostics. The techniques range from widely used basic assays to methods that are specialized for mutational analysis and specific disorders. Readily reproducible, these powerful methods can be used to screen for such inherited disorders as hemophilia A and B, von Willebrand's Disease, factor XI and antithrombin deficiency, protein S deficiency, factor V Leiden mutation, and other problems. Hemostasis and Thrombosis Protocols reflects the many major advances that have occurred in our understanding of the molecular genetics of normal hemostasis and its variants. It enables experienced and novice investigators readily to master the complexities of research on molecular hemostasis and thrombosis, as well as work toward the development of new molecular diagnostics.
