Andrew Ward and a team of experienced researchers have brought together a collection of optimized classic and vanguard techniques for the identification and analysis of imprinted genes. Protocols are included for identifying and cloning imprinted genes, for analyzing imprinted gene expression, for the study of DNA methylation and methylation-sensitive DNA-binding proteins, and for examining chromatin structure. There are also methods for the manipulation of mouse embryos to produce monoparental embryos and embryonic stem cells, and for the generation of transgenic mice with BAC, PAC,and YAC constructs. Each technique is described in step-by-step detail to ensure successful results.
