A solid-phase extraction procedure for DNA purification.
Abstract
The preparation and use of particulate materials for the removal of proteins from nucleic acid samples by solid-phase extraction procedures are described. The solid-phase extraction procedure is analogous to the classical phenol extraction for DNA purification, with the exception that the phenol is replaced with insoluble particulate materials that are chemically similar to phenol and thus function in an analogous manner. These particulate materials have a very high affinity for proteins and a very low affinity for nucleic acids. With these materials, it is possible to remove large quantities of proteins (i.e., tens of milligrams) from minute quantities (submicrogram) of nucleic acid and quantitatively recover the latter in a biologically active state. Compared to other procedures that are currently used to purify nucleic acids, the protocols using these materials offer the advantages of speed, quantitative DNA recovery, safety, and convenience.
