CTCF (CCCTC-binding factor (zinc finger protein)) Antibody

• Catalog#: ARP38820_P050
• Accession#: NP_006556
• Size: 50µg

Description: 
CTCF is 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 CTCF have been associated with invasive breast cancers, prostate cancers, and Wilms' tumors.This gene is a member of the BORIS + CTCF gene family and encodes a transcriptional regulator protein with 11 highly conserved zinc finger (ZF) domains.

Antigen Specificity:  Polyclonal antibody produced in rabbits immunized with a synthetic peptide corresponding to a region of Human CTCF with an internal ID of P21028  Reconstitution and Storage:  Antibody is lyophilized from PBS buffer with 2% sucrose. Add 50 µl of distilled water. Final antibody concentration is 1 mg/ml. For longer periods of storage, store at -20°C. Avoid repeat freeze-thaw cycles.  Key Reference:  Defossez,P.A., (2005) J. Biol. Chem. 280 (52), 43017-43023  Quality Control:  Rabbit Ig G is purified by peptide affinity chromatography method.  Suggested starting concentrations are provided. Optimal dilutions should be determined by end-user. Differences in calculated versus apparent molecular weight may be due to post-translational modifications or protein hydrophobicity. For research use only not for diagnostic, human, or veterinary use.

Western Blot Suggested dilution at 1µg/ml in 5% skim milk / PBS buffer, and HRP conjugated anti-Rabbit IgG should be diluted in 1: 50,000 - 100,000 as second antibody. Immunoblot ARP38820-QC8499-WB.jpg
