This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI). RFFL, also known as Rififylin, RING finger and FYVE-like domain-containing protein 1, FYVE-RING finger protein, Sakura, Fring, Caspases-8 and -10-associated RING finger protein 2, CARP-2, Caspase regulator CARP2, RING finger protein 189 and RING finger protein 34-like, is a novel modulator of NF-kB activation.  RFFL possesses E3 ubiquitin protein ligase activity and has been shown to regulate the levels of CASP8 and CASP10 by targeting them for proteasomal degradation. RFFL also possesses anti-apoptotic activity and may bind phosphatidylinositol phosphates. RFFL is a membrane bound cytoplasmic protein that is expressed ubiquitously. RFFL can be detected in spleen, thymus, prostate, testis, ovary, small intestine, colon and peripheral blood leukocytes and is rapidly degraded after stimulation with TNFSF10, and probably by caspases. Multiple transcript variants have been detected for this protein. Anti-RFFL Antibody is useful for researcher interested in Cancer, Immunology, transcription, and TNF-alpha/NF-kB research.

Application Note

This protein A purified antibody has been tested for use in ELISA, immunohistochemistry and western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 41 kDa in size corresponding to RFFL protein by western blotting in the appropriate tissue or cell lysate or extract.  Isoforms 2 and 3 are 39.7 and 36.6 kDa, respectively and should also cross react with this antibody.


This protein A purified antibody is directed against human RFFL protein. The product was purified from monospecific antiserum by protein A chromatography followed by exhaustive dialysis against the buffer stated above.
