Gene Information
human ... CTCF(10664)
General description
Approx. 120 kDa
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.
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.
Biochem/physiol Actions
Predicted to cross-react with mouse, rat, dog and primates based on sequence homology.
Recognizes CTCF at a.a. 659-675.
Physical form
Rabbit polyclonal antiserum containing 0.05% sodium azide and 30% glycerol.
Preparation Note
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.

Analysis Note
Control
Positive Antigen Control: Catalog #12-309, Hela cell nuclear extract. Add an equal volume of Laemmli reducing sample buffer to 10 µL of extract and boil for 5 minutes to reduce the preparation. Load 20 µg of reduced extract per lane for minigels.
