Abstract

Here we describe a rapid method for extracting DNA from dried brown algae material using a microtitre plate system in conjunction with a milling instrument. The method allows the preparation of nuclear and organelle DNA of quality suitable for polymerase chain reaction amplification. It combines high throughput with low cost per sample: DNA from 192 samples can be extracted in c. 3 h for < €0.40 per sample, nearly tenfold cheaper than commercially available kits. Furthermore, by using microtitre plates, efficient storage and downstream processing is facilitated.
