Specificity: Species cross-reactivity: Human. Other species have not been tested. Reactivity with mouse (but not X. laevis) CTCF is expected owing to similarity of sequence between this ortholog and human CTCF at the site to which the epitope maps.
Immunogen: A synthetic peptide mapping to a region between residues 150 and 200 of human CCCTC-binding factor using the numbering given in entry NP_006556.1 (GeneID 10664).
