      DescriptionChIPAb+ CTCF - ChIP Validated Antibody and Primer Set
      OverviewAll 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+ CTCF set includes the CTCF antibody, a negative control antibody (normal mouse IgG), and qPCR primers which amplify a 165 bp region of human H19 internal control region. The CTCF and negative control antibodies are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of CTCF-associated chromatin.

      Background InformationCTCF, also known as CCCTC-binding factor, contains 11 zinc finger (ZF) binding domains that allow it to bind different DNA target sequences and proteins. This multifunctional protein can act as a transcriptional activator or repressor. As a transcriptional repressor, CTCF, binds to promoters of vertebrate c-myc gene. It also binds to the PLK and PIM1 promoters. CTCF may prevent the access of transcriptional activators to enhancers. CTCF also acts as a transcriptional activator of APP. It is involved in different aspects of gene regulation including promoter activation or repression, hormone-responsive gene silencing, methylation-dependent chromatin insulation, and genomic imprinting. Mutations of CTCF in this gene have been associated with invasive breast cancers, prostate cancers, and Wilms tumors, suggesting a role for CTCF may as a tumor suppressor.

      • Western Blotting
      • Dot Blot
      • Immunohistochemistry
      • Immunoprecipitation
      • Enzyme Immunoassay (ELISA)
      • Multiplexing
      • Chromatin Immunoprecipitation (ChIP)
      Application NotesChromatin Immunoprecipitation:
      Sonicated chromatin prepared from HeLa cells (1 X 106 cell equivalents per IP with 15 min fixation) were subjected to chromatin immunoprecipitation using 2 µg of either Normal Mouse IgG or 2 µg of Anti-CTCF and the Magna ChIP™ G Kit (Cat. # 17-611).
      Successful immunoprecipitation of CTCF associated DNA fragments was verified by qPCR using ChIP Primers, Human H19 ICR as a positive locus, and a representative published negative locus (Wendt, K.S., et al., 2008) (Please see figures). 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.

      Entrez Gene Number
      Entrez Gene SummaryThis gene is a member of the BORIS + CTCF gene family and encodes a transcriptional regulator protein with 11 highly conserved zinc finger (ZF) domains. This nuclear protein is able to use different combinations of the ZF domains to bind different DNA target sequences and proteins. Depending upon the context of the site, the protein can bind a histone acetyltransferase (HAT)-containing complex and function as a transcriptional activator or bind a histone deacetylase (HDAC)-containing complex and function as a transcriptional repressor. If the protein is bound to a transcriptional insulator element, it can block communication between enhancers and upstream promoters, thereby regulating imprinted expression. Mutations in this gene have been associated with invasive breast cancers, prostate cancers, and Wilms' tumors. [provided by RefSeq].

      Note: Poly(ADP-ribosyl)ated isoform, C-terminal truncation, or sumoylation will cause variable migration of CTCF protein on SDS–PAGE, which may present CTCF with different molecular weight on Western Blot. Modifications are dependent on cell type and growing condition.
