Application Abreviews Notes
WB 1/100 - 1/500. Predicted molecular weight: 98 kDa.
IHC-P 1/10 - 1/50. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC/IF 1/10 - 1/50.


  • Function
    Component of the nuclear body, also known as nuclear domain 10, PML oncogenic domain, and KR body. May be involved in the pathogenesis of acute promyelocytic leukemia and viral infection.
  • Tissue specificity
    High levels in spleen and peripheral blood leukocytes, much lower levels in thymus, prostate, ovary, small intestine, and colon. Very low levels in heart, brain, placenta, lung, liver, skeletal muscle, kidney, and pancreas.
  • Sequence similarities
    Contains 1 bromo domain.
    Contains 1 HSR domain.
    Contains 1 PHD-type zinc finger.
    Contains 1 SAND domain.
  • Cellular localization
    Nucleus. Cytoplasm. Localized to nuclear structures termed LANDS, for LYSp100-associated nuclear domains. LANDS are globular, electron-dense structures most often found in the nucleoplasm, but also found at the nuclear membrane and in the cytoplasm, suggesting that these structures may traffic between the cytoplasm and the nucleus.

  • Immunohistochemical analysis of formalin-fixed, paraffin-embedded Human kidney tissue labeling SP140 with ab171141 at 1/10 dilution, followed by peroxidase conjugation of the secondary antibody and DAB staining.

  • Anti-SP140 antibody (ab171141) at 1/100 dilution + HL60 cell line lysate at 35 µg

    Predicted band size: 98 kDa

  • Confocal immunofluorescent analysis of Hela cells labeling SP140 with ab171141 at 1/25 dilution. Hela cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.1%, 10 min), then incubated with ab171141  (1/25, 1 h at 37°C). For secondary antibody, Alexa Fluor® 488 conjugated donkey anti-rabbit antibody (green) was used (1/400, 50 min at 37°C).  Cytoplasmic actin was counterstained with Alexa Fluor® 555 (red) conjugated Phalloidin (7units/ml, 1 h at 37°C).  Nuclei were counterstained with DAPI (blue) (10 µg/ml, 10 min).
