Abstract
Examination of DNA variation is central to understanding the function of mammalian cells, tissues, and whole bodies. Extraction of high-quality DNA from cells and tissues is necessary for innumerable different experiments. We present protocols for the extraction of DNA from both fresh samples and formalin-fixed tissue. Methods for extracting DNA have been standardized and streamlined over the past couple of decades and many extraction kits are available for a reasonable cost. In addition, many of the extraction procedures can also be automated for even higher throughput sample preparation. © 2023 The Authors. Current Protocols published by Wiley Periodicals LLC. Basic Protocol 1: DNA isolation from whole blood, tissue, and cultured cells Alternate Protocol: DNA extraction using automated machines Basic Protocol 2: DNA isolation from saliva and buccal swabs Basic Protocol 3: DNA isolation from formalin-fixed, paraffin-embedded tissue.
