Description

HDAC2 (Histone deacetylase 2) plays a central role in epigenetic regulation by removing acetyl groups from histone lysine residues, leading to chromatin condensation and transcriptional repression. As a key member of the class I histone deacetylase family, HDAC2 influences diverse biological processes including cell cycle progression, differentiation, and apoptosis, making it a critical target for researchers investigating epigenetic mechanisms in cancer, cardiovascular disease, and stem cell biology.

This recombinant monoclonal antibody, generated from clone 9E9, offers the reproducibility and consistency that demanding epigenetic studies require. Because the antibody sequence is defined and produced recombinantly in rabbit, researchers can expect reliable performance across experiments and between lots, eliminating the variability often encountered with traditional hybridoma-derived antibodies. Affinity chromatography purification ensures high specificity for your target.

Validation studies demonstrate robust performance across multiple experimental platforms. In western blot applications, this antibody detects HDAC2 across a broad panel of human cell lines including HeLa, HepG2, Jurkat, MCF-7, and K562, with recommended dilutions ranging from 1:500 to 1:5000. The observed band at approximately 60 kDa runs slightly higher than the predicted molecular weight of 52-56 kDa, which is consistent with post-translational modifications such as phosphorylation or sumoylation known to occur on HDAC2. For tissue-based studies, immunohistochemistry validation in paraffin-embedded human breast cancer tissue confirms nuclear localization patterns at dilutions of 1:50 to 1:200, supporting investigations into HDAC2's role in tumor biology.

Whether you're exploring epigenetic regulation, cardiovascular signaling pathways, or stem cell differentiation mechanisms, this antibody provides a dependable tool for advancing your research.

Target Background

Function

Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Forms transcriptional repressor complexes by associating with MAD, SIN3, YY1 and N-COR. Interacts in the late S-phase of DNA-replication with DNMT1 in the other transcriptional repressor complex composed of DNMT1, DMAP1, PCNA, CAF1. Deacetylates TSHZ3 and regulates its transcriptional repressor activity. Component of a RCOR/GFI/KDM1A/HDAC complex that suppresses, via histone deacetylase (HDAC) recruitment, a number of genes implicated in multilineage blood cell development. May be involved in the transcriptional repression of circadian target genes, such as PER1, mediated by CRY1 through histone deacetylation. Involved in MTA1-mediated transcriptional corepression of TFF1 and CDKN1A.
