This volume is an invaluable guide to the full spectrum of HLA-related science while also serving as a conceptual and technical resource for those involved in HLA-related research and in clinical or surgical practice. In addition, it will be a primary point of contact for individuals working in other areas who suddenly find that their research is drawing them into the complexities of HLA genetics.
