Anti-CTCF Antibody

Raised in rabbit and purified by affinity chromatography, this polyclonal reagent from Antibodies.com targets the chromatin organizer CTCF (CCCTC-binding factor), a zinc-finger transcriptional regulator implicated in chromatin looping, insulator function and gene-expression control. The preparation is supplied at 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol as a cryoprotectant, and is offered here in a 50 µl format that is unconjugated and intended for research use only. Validated applications on the supplier listing are Western blot (WB) and immunohistochemistry (IHC), making the antibody suitable for detection of endogenous CTCF across mammalian samples. Reactivity has been confirmed against human, mouse and rat specimens, supporting cross-species studies in cell-line, primary-tissue and animal-model workflows. Shipped on blue ice from the Antibodies.com distribution network, the reagent should be stored short term at 4 °C and long term at -20 °C in small aliquots to preserve activity, with sodium azide present as a microbial preservative. The host species is rabbit, clonality is polyclonal, and the target is full-length CTCF, giving researchers a flexible primary antibody for chromatin, transcription and epigenetics investigations.
