โฆ Synopsis
We present a simple method for the isolation of DNA from agarose gels that is economic, fast, and independent of electrical equipment. DNA fragments of up to 6 kb can be easily extracted within 5 min using a disposable plastic syringe and filter paper. Total extraction of DNA fragments between 10 and 20 kb in size is achieved by concentrating the DNA flushed from the gel in a DNA-binding column.

After electrophoresis, DNA can be efficiently recovered by solubilization of agarose gels with NaC104, followed by retention of DNA on glass fiber filters. After removal of the NaCIO, by ethanol, the DNA can be extracted with a low salt buffer.
A method is described which allows the obtention of total DNA from cells of Chlamydomonas reinhardi in 1 day. It is based on the gel filtration on agarose of crude lysates incubated for 1 hr with pronase and subsequently brought to 2 M NaCl in order to dissociate nucleoprotein complexes. The DNA ob
