The AGT Cytogenetics Laboratory Manual

Cytogenetics is the study of chromosome morphology, structure, pathology, function, and behavior. The field has evolved to embrace molecular cytogenetic changes, now termed cytogenomics. Cytogenetics is a segment of the evolving cytogenomic branch of genetics that explores the genetic makeup of a cell, in particular chromosomes both in metaphase and in interphase cycles, as well as at the molecular level. It utilizes an assortment of procedures to illuminate both the full complement of chromosomes and a targeted region within a specific chromosome. These investigative tools include routine analysis of G-banded chromosomes, specialized stains that address specific chromosomal structures, and molecular probes, such as fluorescence in situ hybridization and chromosome microarray analysis, which employ a variety of methods to highlight a region as small as a single, specific genetic sequence under investigation. The AGT Cytogenetics Laboratory Manual, Fourth Edition offers a comprehensive treatment of the diagnostic tests offered by this clinical laboratory environment and explains the scientific theories behind those procedures. One of the most valuable assets is its rich compilation of laboratory-tested protocols currently being used in leading laboratories, along with practical advice for nearly every area of interest to cytogeneticists. In addition to covering essential topics that have been the backbone of cytogenetics for over 60 years, such as the basic components of a cell, use of a microscope, human tissue processing for cytogenetic analysis (prenatal, constitutional, and neoplastic), laboratory safety, and the mechanisms behind chromosome rearrangement and aneuploidy, this edition introduces new and expanded chapters that reflect the intuitive experience of its…
