ELISA (1/4000). Western blot (0.3-1 μg/mL). Immunohistochemistry on Paraffin Sections (3.75 μg/mL). This antibody validated for use in Immunohistochemistry on a panel of 21 formalin-fixed,paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0citrate buffer. After incubation with the primary antibody, slides were incubated withbiotinylated secondary antibody, followed by alkaline phosphatase-streptavidin andchromogen. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

RING1B (also known as BAP1, DING, Polycomb-M33 interacting protein Ring1B, Ring finger protein 1b, Ring finger protein 2 and RNF2) is one of the PcG proteins. The polycomb group (PcG) of proteins form the multiprotein complexes that are important for the transcription repression of various genes involved in development and cell proliferation. It has been shown to interact with, and suppress the activity of, transcription factor CP2 (TFCP2/CP2). Studies of the mouse counterpart suggested the involvement of this gene in the specification of anterior-posterior axis, as well as in cell proliferation in early development. This protein was also found to interact with huntingtin interacting protein 2 (HIP2), a ubiquitin-conjugating enzyme that possesses ubiquitin ligase activity.Synonyms: BAP-1, BAP1, DING, E3 ubiquitin-protein ligase RING2, HIP2-interacting protein 3, HIPI3, Protein DinG, RING finger protein 2, RING1B
