Histone Modification Antibodies

Histone Modification Antibodies recognize post-translational changes on histone proteins that influence chromatin accessibility and gene regulation. Methylation, acetylation, phosphorylation, ubiquitination, citrullination, and related histone marks can affect nucleosome interactions, recruitment of reader proteins, transcriptional activation or repression, DNA repair, replication, and chromosome structure.

These antibodies support detection of site-specific histone marks, histone-modifying enzyme activity, and chromatin states associated with cell identity, development, stress response, and disease biology. Histone mark analysis is important for ChIP, western blotting, immunofluorescence, immunohistochemistry, and other workflows that link chromatin modifications with genomic function.
