Isolation of DNA from Plants A Comparison of Maxwell®

Traditionally, CTAB (hexadecyltrimethylammonium bromide) has been the gold-standard method for genomic DNA purification from plant material because of low cost and availability. However, home-brew CTAB methods are time-consuming and laborious to perform, and can result in inconsistencies in purification that lead to failed isolation.
