Unlock the full potential of Reader CUT&RUN with our high-affinity CUTANA™ Anti-GST Tag Antibody, specifically developed to support chromatin profiling applications wherein a GST-tagged reader protein replaces the traditional primary antibody in directing the selective cleavage and release of target chromatin fragments by pAG-MNase [1]. For example, this antibody is used in CUTANA™ meCUT&RUN, a modified CUT&RUN workflow in which a GST-tagged MeCP2 methyl binding domain is used to enrich regions of chromatin with symmetrically methylated CpGs, enabling streamlined, high-resolution mapping of DNA methylation.

Engineered for superior performance in low-background, high-resolution CUT&RUN assays, this antibody offers exceptional sensitivity and specificity for detecting GST-fusion proteins bound to chromatin. Whether studying histone modifications, DNA methylation, or other epigenetic readers, this antibody is the ideal tool for enabling precise, reproducible mapping using GST-tagged fusion constructs.

Figure 1: meCUT&RUN DNA fragment size distribution analysis
meCUT&RUN was performed as described in Figure 4. Library DNA was analyzed by Agilent TapeStation®. This analysis confirmed that mononucleosomes were predominantly enriched in meCUT&RUN (~300 bp peaks represent 150 bp nucleosomes + sequencing adapters).

Figure 2: Gene browser tracks
meCUT&RUN was performed as described in Figure 4. A 30 kb window at the AJM1 gene is shown for anti-GST antibody and meCUT&RUN. Tracks are also shown with representative data for meCUT&RUN followed by EM-seq (meCUT&RUN-EM) and whole genome EM-seq (WGEM), using the New England Biolabs NEBNext® Enzymatic Methyl-seq v2 Kit (NEB E8015). The meCUT&RUN kit produced the expected genomic distribution, showing enrichment of methylated DNA that approximates the methylated CpG pattern observed in WGEM. Images were generated using the Integrative Genomics Viewer (IGV, Broad Institute).
