Anti-Aurora A (phospho T288) antibody (ab18318)


  • Product nameAnti-Aurora A (phospho T288) antibody
    See all Aurora A primary antibodies
  • Description
    Rabbit polyclonal to Aurora A (phospho T288)
  • SpecificityThis antibody has been shown to mildly react with Aurora B if excess antibody is applied (cross-reactivity with Aurora B can be observed in immunofluorescence)
  • Tested applicationsSuitable for: WB, ICC/IFmore details
  • Species reactivity
    Reacts with: Human
  • Immunogen

    Synthetic peptide: SRRTTPLCGT, corresponding to amino acids 284-292 of Human Aurora A

  • Positive control
    • Nocadozole-arrested HeLa cell lysate immunoprecipitate with a pan-Aurora A monoclonal antibody (clone 35C1)(ab13824)
  • General notesHela cells were synchronized to M phase using nocadazole (18 hrs treatment). Mitotic shake-off cells were used to prepare extracts. For a 10 cm2 dish (approximately 80% confluent, about 60% in M-phase), typically 2-4 lanes would be loaded for Western blot. Phosphorylated Aurora A can be difficult to detect, you may want to IP first with pan-Aurora A before blotting with the phospho-specific antibody.



Our Abpromise guarantee covers the use of ab18318 in the following tested applications.

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

Application Abreviews Notes
WB 1/500. Detects a band of approximately 46 kDa (predicted molecular weight: 46 kDa). It is strongly recommended that immunoprecipitation with a pan-specific Aurora antibody be carried out before Western blotting with the phospho-specific antibody to increase signal. Weak non specific bands can be sometimes observed above the band of interrest. A large non specific band is also present just above 32kDa.
ICC/IF 1/500 - 1/1000.


  • FunctionContributes to the regulation of cell cycle progression. Required for normal mitosis. Associates with the centrosome and the spindle microtubules during mitosis and functions in centrosome maturation, spindle assembly, maintenance of spindle bipolarity, centrosome separation and mitotic checkpoint control. Phosphorylates numerous target proteins, including ARHGEF2, BRCA1, KIF2A, NDEL1, PARD3, PLK1 and BORA. Regulates KIF2A tubulin depolymerase activity (By similarity). Required for normal axon formation. Plays a role in microtubule remodeling during neurite extension. Important for microtubule formation and/or stabilization.
  • Tissue specificityHighly expressed in testis and weakly in skeletal muscle, thymus and spleen. Also highly expressed in colon, ovarian, prostate, neuroblastoma, breast and cervical cancer cell lines.
  • Sequence similaritiesBelongs to the protein kinase superfamily. Ser/Thr protein kinase family. Aurora subfamily.
    Contains 1 protein kinase domain.
  • Post-translational
    Activated by phosphorylation at Thr-288; this brings about a change in the conformation of the activation segment. Phosphorylation at Thr-288 varies during the cell cycle and is highest during M phase. Autophosphorylated at Thr-288 upon TPX2 binding. Phosphorylated upon DNA damage, probably by ATM or ATR.
    Ubiquitinated by CHFR, leading to its degradation by the proteasome (By similarity). Ubiquitinated by the anaphase-promoting complex (APC), leading to its degradation by the proteasome.
  • Cellular localizationCytoplasm > cytoskeleton > centrosome. Cytoplasm > cytoskeleton > spindle pole. Detected at the neurite hillock in developing neurons (By similarity). Localizes on centrosomes in interphase cells and at each spindle pole in mitosis.

Anti-Aurora A (phospho T288) antibody images

  • Predicted band size : 46 kDa
    Extracts from untreated Hela cells (Lane 1) or overnight nocodazole-treated Hela cells (Lane 2) were immunoprecipitated with a pan-Aurora A monoclonal antibody (clone 35C1) (available as ab13824), resolved by electrophoresis, transferred to nitrocellulose and probed with rabbit polyclonal antibody against Thr288 phosphorylated Aurora A (ab18318). Proteins were visualized using a donkey anti-rabbit secondary conjugated to HRP (available as ab16284), and a chemiluminescence detection system

  • Predicted band size : 46 kDa
    The blot shown above was stripped and reprobed with pan-Aurora specific polyclonal antibody (available as ab12875) to verify equal loading of Aurora A in the extracts. Proteins were visualized using a donkey anti-rabbit secondary conjugated to HRP (available as ab16284)and a chemiluminescence detection system.
  • Immunofluorescence analysis of P. mammillata embryos during mitotic cycle, staining Aurora A (phospho T288) with ab18318.

    Embryos were fixed in methanol/1%formaldehyde (-20°C) overnight, permeabilized in 0.25% Triton X-100 for 15 minutes at room temperature and then incubated in primary antibody (1/200) in PBS/1%BSA overnight at 4°C. A FITC-conjugated anti-rabbit IgG (1/50) was used as the secondary antibody.
  • Prometaphase HeLa cells were permaeabiliased in 0.2% Triton-X100 and fixed for 10 minutes at room temperature in 4% formaldehyde. The cells were washed 3 times in PBS and incubated with ab18318 (1/1000) for 1 hour at room temperature. The panel of images shows the nuceli stained with DAPI (blue) and the centromeres stained with ab18318 (green). 100x magnification.
