Applications

Target

• FunctionThought to be required for maintaining cell proliferation.
• Sequence similaritiesContains 1 FHA domain.
• Developmental stageExpression of this antigen occurs preferentially during late G1, S, G2 and M phases of the cell cycle, while in cells in G0 phase the antigen cannot be detected.
• Cellular localizationNucleus. Nucleus > nucleolus. Chromosome. Predominantly localized in the G1 phase in the perinucleolar region, in the later phases it is also detected throughout the nuclear interior, being predominantly localized in the nuclear matrix. In mitosis, it is present on all chromosomes.

  Immunocytochemistry/ Immunofluorescence - Anti-Ki67 antibody - Proliferation Marker (ab15580)
  ab15580 staining Ki67 in SK-N-SH cells treated with NADA (N-Arachidonyldopamine) (ab120099), by ICC/IF. Decrease in Ki67 expression correlates with increased concentration of NADA (N-Arachidonyldopamine), as described in literature.
  The cells were incubated at 37°C for 10 minutes in media containing different concentrations of ab120099 (NADA (N-Arachidonyldopamine)) in ethanol, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab15580 (1 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

  Immunofluorescence - Ki67 antibody - Proliferation Marker (ab15580)Kirk McMannus, University of British Columbia

  SK-N-SH cells were permitted to grow to confluency, then serum starved for 48 hours and predominantly driven into G0. The cells were then paraformaldehyde fixed and immunofluorescently labelled with anti-Ki67 (ab15580) at a dilution of 1/1000. The majority of the cells show little or no Ki67 staining, indicating they are in G0 arrest (red cells). Two cells however show strong nucleolar Ki67 staining indicating they are still cycling (green cells). The DNA is stained with DAPI and is shown in red. The Ki67 staining is shown in green. x 63 magnification.

  Similar results were seen with an asynchronous population of HeLa cells. The Ki67 staining was localised to the periphery of the nucleoli and throughout the nucleoplasm of proliferating cells. (This data is not shown but is available upon request).

  ab15580 at 1/50 staining Human umbilical artery endothelial cells by ICC/IF. The tissue was paraformaldehyde fixed and blocked before permeabilization with saponin and incubation with the antibody for 16 hours. A FITC conjugated goat anti-rabbit IgG was used as the secondary. The merged image shows those cells expressing Ki67 from the total number of exponential cells.

  IHC image of ab15580 stained human skin carcinoma FFPE section. Section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH6) for 30 seconds at 125°C. Section was incubated with ab15580 at a dilution of 1:200 for 1h at room temperature and detected using an HRP conjugated polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab15580, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  IHC image of ab15580 staining in mouse spleen formalin fixed paraffin embedded tissue section, performed on a Leica Bond^TM system using the standard protocol B. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab15580, 1µg/ml, for 15 mins at room temperature. A goat anti-rabbit biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
  
  For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
