Anti-BORIS antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. BORIS (Brother of the Regulator of Imprinted Sites) also known as  CCCTC-binding factor-like protein, is  normally only expressed in the testis and expressed in a mutually exclusive manner with CTCF during male germ cell development.  However, previous studies have shown that BORIS is abnormally activated in a wide range of human cancers.  Expression of BORIS in normally BORIS-negative cells promotes cell growth that may lead to transformation.  BORIS maps to the cancer-associated amplification region thought to contain an oncogene or dominant-immortalizing gene. BORIS is a candidate protein for the epigenetic reprogramming factor acting in the male germ line.  BORIS is found in both the nucleus and cytoplasm. BORIS antibody can be used to investigate epigenetic regulation.

Application Note

BORIS affinity purified antibody has been tested for use in ELISA and by western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a predominant band approximately 75 kDa in size corresponding to BORIS by western blotting in the appropriate cell lysate or extract.


This affinity-purified antibody is directed against the human BORIS protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification.  A BLAST analysis was used to suggest cross reactivity with BORIS proteins from human and chimpanzee.  Partial reactivity may occur against BORIS from mouse, dog and rat sources based on varying degrees of homology to the immunizing sequence.  Reactivity against homologues from other sources is not known.
