Gene Information
human ... CTCF(10664)
General description
CTCF is a ubiquitous 11 zinc finger (ZF) protein with highly versatile functions. 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. CTCF may also act as tumor suppressor. CTCF organizes epigenetically controlled chromatin insulators that regulate imprinted genes in soma.
Specificity
Predicted to cross-react with mouse, rat, dog and primates based on sequence homology.
Recognizes CTCF at a.a. 659-675.
Immunogen
KLH-conjugated, synthetic peptide corresponding to amino acids 659-675 (C-TNQPKQNQPTAIIQVED) of human CCCTC-binding factor (CTCF) with a N-terminal cysteine added for conjugation purposes.
Application
Chromatin Immunoprecipitation:
An independent laboratory has confirmed that this antibody immunoprecipitates CTCF-bound chromatin from WEHI B-cells.
An independent laboratory has confirmed that this antibody immunoprecipitates CTCF-bound chromatin from WEHI B-cells.
Use Anti-CTCF Antibody (Rabbit Polyclonal Antibody) validated in ChIP, WB, ChIP-seq to detect CTCF also known as 11-zinc finger protein, CCCTC-binding factor.
Quality
Routinely evaluated by Western Blot.
Western Blot Analysis:
A 1:1000–1:5000 dilution of this lot detected CTCF in HeLa nuclear extract. A previous lot detected CTCF in K562 nuclear extract (data not shown).

Linkage
Replaces: MABE547
Physical form
Rabbit polyclonal antiserum containing 0.05% sodium azide and 30% glycerol.
Storage and Stability
Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C.
Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.

CTCF is a transcriptional repressor of the c-myc gene. Although CTCF has been characterized in some detail, there is very little information about the regulation of CTCF activity. Therefore we investigated CTCF expression and phosphorylation during induced differentiation of human
