Spinal tap — using cactus spines to isolate DNA

In the family Cactaceae, isolation of genetic material can be difficult due to the presence of polysaccharide-based mucilage content and other secondary compounds. Although important for water storage, these compounds necessitate the use of toxic chemicals and numerous modifications to DNA extraction protocols. Shannon D. Fehlberg and colleagues describe a novel method for isolation of DNA using cactus spines in the March issue of Applications in Plant Sciences.
