This article demonstrates a detailed protocol for DNA isolation and high-throughput sequencing library construction from herbarium material including rescue of exceptionally poor-quality DNA.
The protocol describes the preparation of cell membrane affinity chromatography (CMAC) columns with immobilized cell membrane fragments containing functional transmembrane tropomyosin kinase receptor B proteins. The use of CMAC columns in the identification of specialized plant metabolites interacting with these receptors and present in complex natural mixtures is also explained.
