Preparing Cellular DNA from Nuclei or Whole Cells
Cold Spring Harbor Protocols
|September 3, 2015
Abstract:
It is often desirable to have cellular DNA on hand. DNA is stable and can be maintained intact for many years. This protocol describes the preparation of DNA from nuclei after the cytoplasmic extract has been removed. The resulting DNA is suitable for polymerase chain reactions and Southern blots to determine copy number and sites of integration of plasmids in stable cell lines. Quantitation of DNA may not be exact because RNA is not completely removed. The method can also be used on whole cells, but there will be more RNA contamination.

DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...
