  • Positive control
    • Nuclear/whole extract of human HeLa cells.
  • General notesIf slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours. There is some debate about whether this antibody is suitable for use in IF and we would be most interested to hear from researchers who test this antibody in this application. The antibody has been reported to be suitable for use in IF at a dilution of 1/100 using HeLa cells (see image below). However, one of our customers used this product in HeLa cells and reported an unusual staining pattern - please see the enquiries section of the online datasheet for further details.



Our Abpromise guarantee covers the use of ab12183 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • FunctionComponent of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly. Probably acts through association with AURKB or AURKC. Seems to bind directly to microtubules. Controls the kinetochore localization of BUB1.
  • Sequence similaritiesBelongs to the INCENP family.
  • Cellular localizationChromosome > centromere. Cytoplasm > cytoskeleton > spindle. Nucleus. Chromosome > centromere > kinetochore. Localizes to inner kinetochore. Localizes on chromosome arms and inner centromeres from prophase through metaphase and then transferring to the spindle midzone and midbody from anaphase through cytokinesis. Colocalizes with AURKB at mitotic chromosomes.

Anti-INCENP antibody images

  • HeLa cells were fixed for 10mins in fresh 3.7% paraformaldehyde, permeabilised with PBS + 0.1% Triton X 100, and blocked with 1% goat serum in Abdil. The primary antibody (in Abdil) was incubated OVERNIGHT (1 hour didn't work) at room temperature at a dilution of 1/150. The cells were co-stained with mouse anti-tubulin (secondary is Anti-Mouse Alexa 488) and ACA (Human anti centromere marker, secondary is Anti-Human Cy5) and DAPI. The figure shows projected images of dividing cells (prophase, prometaphase, metaphase, anaphase, telophase). The top panels show ab12183, DNA and microtubule stains. The lower panels are the same cells, showing a subset of optical sections at higher magnification. ACA (geen) stains centromeres and ab12183 (red) stains the inner centromere in prophase, prometaphase, and metaphase. The ab12183 channel has been linerally scaled to reduce the background staining associated with this antibody.
  • Demembranated sperm nuclei and CSF (cytostatic factor-arrested) low-speed egg extracts were prepared in XB and reacted at room temperature as described. Proteins were added to extract prior to sperm addition or else immediately after sperm addition into XB buffer (100 mM KCl, 1 mM MgCl2, 0.1 mM CaCl2, 10 mM K-HEPES pH 7.7, 50 mM sucrose) supplemented with energy mix (3.75 mM creatinine phosphate, 0.5 mM Na2-ATP, 0.5 mM MgCl2, 50 µM EGTA). To label damaged DNA, biotin-16-dUTP was added to metaphase reactions to a final concentration of 40 µM. 30 minutes after sperm addition, reactions were diluted 1/10 into XB supplemented with 1 mM MgCl2, 5 mM EGTA, 0.25% Triton X-100, and 10% formaldehyde and processed for Immunofluorescence. Antibody used ab12183 (red).
  • Immunohistochemistry (Frozen sections) analysis of mouse embryonic skin - keratinocytes tissue sections labeling INCENP with ab12183. Tissue was fixed with paraformaldehyde, permeabilized with 10% Triton-X (0.05% Final) and blocked with Gelatin for 1 hour at 20°C. Samples were incubated with primary antibody (1/200) for 12 hours at 4°C. An undiluted Alexa Fluor 488 donkey anti-rabbit IgG polyclonal was used as the secondary antibody.

I have received confirmation from the source of ab12183 that the antibody will detect a 106 kDa band using whole HeLa extract. They cannot explain why you are detecting a 80kDa band and hypothesize that this could be a splice variant or a lysed form of...
