The best histone PTM antibodies. Period.
EpiCypher takes a unique approach to validating histone post-translational modification (PTM) antibodies. Our exclusive SNAP Spike-in technology is the only method that uses physiological nucleosome controls to directly quantify antibody performance in ChIP, CUT&RUN, and CUT&Tag workflows. The resulting SNAP-Certified™ Antibodies have multiple advantages over competitors:
- Superior target specificity and affinity
- Robust performance in CUT&RUN and CUT&Tag
- Improved PTM profiling from low cell numbers
- Increased reliability through lot-specific testing

If you can’t trust your antibody, you can’t trust your data
Work by EpiCypher and others show that over 70% of ChIP antibodies to histone PTMs have unacceptable rates of cross-reactivity and poor target affinity. These results challenge our understanding of PTM biology and demand new tools for improved chromatin mapping.
SNAP Spike-in Certification is the only method that directly quantifies histone PTM antibody specificity and binding efficiency in genomic mapping assays (see Figure).
Don’t question your results – EpiCypher offers the best PTM antibodies.

Specificity is Crucial
Accurate biological interpretations from CUT&RUN and CUT&Tag assays require specific antibodies.
Standard validation methods cannot distinguish specific vs. nonspecific PTM antibodies. Even highly cited antibodies fail to meet minimal expectations for on-target profiling (see Figure).
SNAP-Certified Antibodies exhibit less than 20% cross-reactivity, ensuring reliable data with exquisite accuracy.
Efficiency Matters
Highly efficient CUT&Tag and CUT&RUN antibodies enable reliable mapping from reduced cell numbers.
However, the historical focus on PTM specificity means that most antibodies lack the efficiency required for low- or single-cell mapping.
SNAP-Certified Antibodies are validated for high efficiency and generate reproducible profiles in cell titrations (see Figure).
