The CTCF Antibody (CAB1133) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, raised in rabbits, has high reactivity with human samples and is validated for use in various applications, including Western blotting.CTCF, also known as CCCTC-binding factor, plays a crucial role in chromatin organization and gene regulation by binding to specific DNA sequences. Its ability to insulate and regulate gene expression makes it a valuable target for studies in epigenetics, gene transcription, and genome function.
This antibody is validated for use in WB, IHC-P, IF/ICC, IP, ChIP, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.

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. 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. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
