General description
All ChIPAb+ antibodies are individually validated for chromatin precipitation, every lot, every time. Each ChIPAb+ antibody set includes control primers (tested every lot by qPCR) to biologically validate your IP results in a locus-specific context. The qPCR protocol and primer sequences are provided, allowing researchers to validate ChIP protocols when using our antibody in their chromatin context. Each set also includes a negative control antibody to ensure specificity of the ChIP reaction.
The ChIPAb+JMJD1C set includes the JMJD1C antibody, a Normal Rabbit IgG, and control primers which amplify a 110 bp region of ChIP Primers, human β-globin. The JMJD1C and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of JMJD1C -associated chromatin.

In the absence of ligands, the corepressor N-CoR represses nuclear hormone receptor-mediated gene transcription. In the presence of ligands, these hormone receptors activate gene expression and play critical roles in development, growth, and homeostasis. N-Cor-mediated transcriptional repression is facilitated through the formation of histone deacetylase (HDACs) N-CoR complexes or by conjugation from small ubiquitin-like modifier 1 (SUMO-1). It is shown that the SANT1 domain of N-CoR serves as a binding region for SUMO-E2 conjugating enzyme Ubc9 and SUMO-E3 ligase Pias1, which is necessary for N-CoR-mediated repression of respective reporter genes. SUMOylation-deficient N-COR knockout mice display a signification reduction in the repression of gene transcription and result in defects involving the differentiation and development of neural cells into erythrocytes and thymocytes.
Immunogen
KLH-conjugated linear peptide corresponding to a region between amino acids 1510 and 1540 of the N-CoR protein.
Application
Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from untreated or UV treated (6 hrs, 50 joules/m2.) U2OS cells (3 X 10E6 cell equivalents per IP) was subjected to chromatin immunoprecipitation using using 3 µg of either Normal Rabbit IgGor 3 µg of Anti-N-CoR and the Magna ChIP A/G Kit (Cat. # 17-10085). Successful immunoprecipitation of N-CoR associated DNA fragments was verified by qPCR using ChIP Primers, p21. (Figure 2). Data is presented as percent input of each IP sample relative to input chromatin for each amplicon and ChIP sample as indicated.
Please refer to the EZ-Magna ChIP A (Cat. # 17-408) or EZ-ChIP (Cat. # 17-371) protocol for experimental details.
Western Blot Analysis:
Representative lot data.
RAW 264.7 cell lysate was probed with Anti-N-CoR (1 µg/mL). Proteins were visualized using a Donkey Anti-Rabbit IgG secondary antibody conjugated to HRP and a chemiluminescence detection system.
Arrow indicates Anti-N-CoR (~270 kDa). (Figure 3).

Transcriptional silencing by many transcription factors is mediated by the nuclear receptor corepressor (N-CoR). The mechanism by which N-CoR represses basal transcription involves the direct or indirect recruitment of histone deacetylases (HDACs). We have isolated two multiprotein N-CoR complexes, designated
