H3.3 Antibody, SNAP-Certified for CUT&RUN is an antibody to histone variant H3.3. H3.3 is enriched in promoters and enhancers of active genes as well as transcriptionally inactive heterochromatin, reflecting the diverse functions of this unique histone variant. The antibody is highly specific for H3.3 without cross-reacting with canonical H3.1. Binding is not impacted by methylation or mutations at amino acids H3.3K27 or H3.3K36.

H3.3 differs from canonical H3.1 at just five amino acids (31, 87, 89, 90, 96). Most of these changes are located in the inaccessible histone core, making them unfit epitopes for chromatin mapping experiments. The SNAP-Certified H3.3 antibody specifically interacts with amino acid 31, where a serine is substituted for alanine, allowing clear distinction between H3.3 and H3.1 in chromatin mapping experiments
