	Western Blot: HDAC3 Antibody [NB100-1669] - Analysis of HDAC3 in HeLa cell lysate with anti-HDAC3 this antibody.
	Immunocytochemistry/Immunofluorescence: HDAC3 Antibody [NB100-1669] - HDAC3 antibody was tested in HeLa cells with Dylight 488 (green). Nuclei were counterstained with DAPI (blue). An antibody dilution of 1:10 was used. Image objective 40x.
	Immunohistochemistry-Paraffin: HDAC3 Antibody [NB100-1669] - IHC analysis of a formalin fixed paraffin-embedded (FFPE) human colon cancer using 1:50 conc. of HDAC3 antibody on a Bond Rx autostainer (Leica Biosystems). The assay involved 20 minutes of heat induced antigen retrieval (HIER) using 10mM sodium citrate buffer (pH 6.0) and endogenous peroxidase quenching with peroxide block. The sections were incubated with primary antibody for 30 minutes and Bond Polymer Refine Detection (Leica Biosystems) with DAB was used for signal development followed by counterstaining with hematoxylin. Whole slide scanning and capturing of representative images was performed using Aperio AT2 (Leica Biosystems). Nuclear staining of HDAC3 was observed. Staining was performed by Histowiz.
	Simple Western: HDAC3 Antibody [NB100-1669] - Simple Western lane view shows a specific band for HDAC3 in 1.0 mg/ml of HeLa lysate. This experiment was performed under reducing conditions using the 12-230 kDa separation system.

Background

Histone deacetylase (HDAC) and histone acetyltransferase (HAT) are enzymes that regulate transcription by selectively deacetylating or acetylating the eta-amino groups of lysines located near the amino termini of core histone proteins. Eight members of HDAC family have been identified in the past several years. These HDAC family members are divided into two classes, I and II. Class I of the HDAC family comprises four members, HDAC-1, 2, 3, and 8, each of which contains a deacetylase domain exhibiting from 45 to 93% identity in amino acid sequence. Class II of the HDAC family comprises HDAC-4, 5, 6, and 7, the molecular weights of which are all about twofold larger than those of the class I members, and the deacetylase domains are present within the C-terminal regions, except that HDAC-6 contains two copies of the domain, one within each of the N-terminal and C-terminal regions. Human HDAC-1, 2 and 3 were expressed in various tissues, but the others (HDAC-4, 5, 6, and 7) showed tissue-specific expression patterns (3). These results suggested that each member of the HDAC family exhibits a different, individual substrate specificity and function in vivo.
