Images

IHC image of CSB-RA943659A0HU diluted at 1:100 and staining in paraffin-embedded human gastric cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.08% DAB.

Description

Histone H3.1, encoded by the HIST1H3A gene cluster, serves as a fundamental component of nucleosome structure and plays a central role in chromatin organization and epigenetic regulation. The lysine 27 position on histone H3 represents one of the most intensively studied epigenetic modification sites, where methylation and acetylation states directly influence gene expression programs, cell fate decisions, and developmental processes. Mutations at this critical residue, particularly the K27M substitution, have emerged as defining features of certain aggressive cancers, making detection of mutated HIST1H3A essential for both basic chromatin biology and translational oncology research.

This recombinant monoclonal antibody, generated from clone 35C11 in rabbit host, offers the reproducibility and consistency that demanding epigenetic studies require. Because the antibody sequence is defined and produced recombinantly, researchers can expect uniform performance across experiments and over time, eliminating the lot-to-lot variability that can complicate longitudinal studies or multi-site collaborations. Affinity chromatography purification ensures high specificity for the target epitope derived from human HIST1H3A.

Validation in immunohistochemistry demonstrates reliable performance in formalin-fixed, paraffin-embedded human gastric cancer tissue, with optimal staining achieved at 1:100 dilution using citrate buffer antigen retrieval. This tissue-based validation confirms the antibody's utility for examining histone H3 mutation status in clinical specimens and tumor samples. The antibody is also validated for ELISA applications, providing flexibility for quantitative detection workflows.

Researchers investigating chromatin dynamics, histone mutations in cancer, or epigenetic mechanisms in human samples will find this antibody a dependable tool for their experimental needs.

Target Background

Function(From Uniprot)

Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.
