Book excerpt: This volume focuses on protein analysis, and covers a wide array of uses of protein microarray for disease analysis. The chapters in this book discuss different stages of protein microarrays from their construction to their use, including different types of protein microarrays such as recombinant proteins, antibody, phage, and NAPPA protein microarrays, in planar format or in solution via beads arrays. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, Protein Microarrays for Disease Analysis: Methods and Protocols is a valuable resource for graduate and post-doctoral fellows interested in protein microarrays, as well as senior researchers interested in gaining more insight into this developing field.
