GST-MeCP2 for meCUT&RUN
Powered by BiozCUTANA™ GST-MeCP2 for meCUT&RUN is a GST-tagged MeCP2 methyl binding domain that is validated to enrich regions of chromatin with symmetrically methylated CpGs in CUTANA™ meCUT&RUN, a modified CUT&RUN workflow that enables streamlined, high-resolution mapping of DNA methylation. meCUT&RUN can be followed by a traditional library prep method, such as the CUTANA™ CUT&RUN Library Prep Kit (EpiCypher 14-1001/14-1002), to provide ~150 bp resolution profiles of DNA methylation enrichment, or by a cytosine conversion strategy such as Enzymatic Methyl-seq (NEB® EM-seq™, preferred) or bisulfite sequencing to provide base-pair resolution of 5-methylcytosine (5mC).

meCUT&RUN was performed starting with 500k K562 cells with either 2.5 µL of 20X GST-MeCP2 added as the primary binding reagent or 0.5 µg of a secondary antibody-only control (anti-GST antibody, EpiCypher 13-0073) to determine background cleavage. Library preparation was performed using 5 ng of meCUT&RUN-enriched DNA (or the total amount recovered if less than 5 ng) using the CUTANA™ CUT&RUN Library Prep Kit (EpiCypher 14-1001/14-1002). Libraries were run on an Illumina NextSeq2000 with paired-end sequencing (2×50 bp). Sample sequencing depth was 7.7 million reads (anti-GST) and 8.4 million reads (GST-MeCP2). Data were aligned to the hg38 genome using Bowtie2. Data were filtered to remove duplicates, multi-aligned reads, and ENCODE DAC Exclusion List regions.
