Background Information
Histone H2B is a core component of the nucleosome, the fundamental unit of chromatin. It forms a dimer with Histone H2A, and two H2A-H2B dimers combine with a (H3-H4)₂ tetramer to create the histone octamer. The primary function of this structure is to package DNA into a compact and manageable form. However, H2B is also subject to various post-translational modifications (PTMs), such as ubiquitination, which serve as epigenetic marks to regulate gene expression by altering chromatin accessibility.

Reviews
What customers say
All three reviews rate the antibody 4 out of 5 stars for Western Blot applications. Users report strong, specific signal around 20–25 kDa in mouse cortex at 1:1000 dilution, with 1:2000 also working well. The antibody successfully detected H2B in Jurkat cells at 1:1000. One user tested it in HEK293 cells at 1:2000 without additional comments. Overall, reviewers find it reliable for detecting H2B across cell lines and tissue with consistent performance at dilutions between 1:1000 and 1:2000.
