Pioneering bench researchers describe in detail the cutting-edge techniques they have developed for analyzing the genomes and gene products in a diverse range of protozoan and metazoan parasites. These readily reproducible techniques can be used in genomic, functional genomic, and post-genomic studies and include transfection methods and vectors for several protozoan parasites, global analysis using microarrays, gene ablation using RNA interference, gene knockout, mutagenesis, and chromosome man
