Product Image Gallery

CTCF Antibody in Immunocytochemistry (ICC/IF) — CTCF antibody (pAb) tested by Immunofluorescence. Formaldehyde fixed HeLa cells stained with CTCF antibody at a 1:2,000 dilution.

CTCF Antibody in Western Blot (WB) — CTCF pAb tested by Western blot. CTCF detection by Western blot. The analysis was performed using 30 µg HeLa nuclear cell extract and CTCF at a 1:500 dilution.

CTCF Antibody in ChIP assay (ChIP) — CTCF antibody (pAb) tested by ChIP analysis. Chromatin IP performed using the ChIP-IT® Express Kit (Catalog No. 53008) and HeLa Chromatin (1.5 x 106 cell equivalents per ChIP) using 8 µl of CTCF antibody or the equivalent amount of rabbit IgG as a negative control. Real time, quantitative PCR (RT-qPCR) was performed on DNA purified from each of the ChIP reactions using a primer pair specific for the SCN4A gene (site A or site B). Data are presented as Fold Enrichment of the ChIP antibody signal versus the negative control IgG (arbitrarily assigned a value of 1) using the ddCT method.

Target Information

Transcriptional factor CTCF is a ubiquitously expressed 11-zinc finger domain containing, DNA-binding nuclear phosphoprotein that is involved in multiple aspects of normal gene regulation including transcriptional repression and activation, gene silencing, chromatin insulation and regulation of imprinted sites. CTCF uses different combinations of ZF domains and interacts with the CCCTC motif on the DNA. It can bind to HAT- and HDAC-containing complexes thereby influencing transcriptional activation or repression respectively. It is a multifunctional protein involved in the transactivation of APPB gene, silencing of c-myc gene, and insulation of human beta-globin and DMI myotonic dystrophy locus and imprinting control of IGF2 and H19 regions. CTCF has also been shown to regulate the transcription of Pax6 and IRAK2 promoter thereby opening a therapeutic avenue. Mutations in this gene have been associated with invasive breast cancers, prostate cancers and Wilms' tumors.
