A Novel Method to Capture Methylated Human DNA from Stool: Implications for Colorectal Cancer Screening
21 Aug 2007
Abstract excerpt
BACKGROUND: Assay of methylated DNA markers in stool is a promising approach for colorectal cancer (CRC) screening. A method to capture hypermethylated CpG islands from stool would enrich target analyte and allow optimal assay sensitivity. METHODS: Methyl-binding domain (MBD) protein was produced using a pET6HMBD plasmid with MBD DNA sequence cloned from rat MeCP2 gene and bound to a column of nickel-agarose...
