Features

• High-affinity binding provides greater sensitivity.
• Elution in a small volume simplifies downstream applications.
• Easy-to-use protocol yields enriched fractions in less than 2 hours.
• Enriched methylated DNA fractions can be easily ligated to double-stranded adaptors for Next Generation Sequencing.
• Highly pure product from a wide range of input DNA concentrations.

Method Overview

Step I—Fragment Genomic DNA 
DNA must be fragmented by sonication, nebulization or enzymatic treatment to an average size of less than 1,000 bp. 

Step II—Combine MBD2-Fc and Protein A Magnetic Beads in 1X Bind/Wash Buffer.
Incubate the reaction for 15 minutes at room temperature. Wash beads two times in Bind/Wash Reaction Buffer. 

Step III—Add fragmented DNA to MBD2-Fc / Protein A Magnetic Beads. 
Incubate the reaction for 20 minutes at room temperature. Wash beads three times at room temperature for five minutes each to remove unbound DNA. 

Step IV—Elute enriched methylated CpG DNA from beads 
Incubate the sample at 65°C for 15 minutes in DNase-free water.
