FAQ: Can the Monarch HMW DNA Extraction Kit for Tissue (NEB #T3060) be used for plant DNA extraction? 

The Monarch HMW DNA Extraction Kit is not currently recommended for extraction of HMW DNA from plants. The lysate of plant samples often contains polysaccharides that will not be removed completely by the Monarch HMW gDNA Tissue Lysis Buffer. The presence of polysaccharides in the lysate hinders binding of the HMW DNA to the glass beads.
