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.

  • ab16667 staining Ki67 in Rat liver tissue sections by Immunohistochemistry (IHC-P - formaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 1% BSA for 2 hours at 22°C. Samples were incubated with primary antibody (1/500 in PBS-T + 1% BSA) for 18 hours at 4°C. A Biotin-conjugated goat anti-rabbit IgG monoclonal (1/2000) was used as the secondary antibody.

  • ab16667 staining Ki67 in wild-type HAP1 cells (top panel) and Ki67 knockout HAP1 cells (bottom panel). The cells were fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab16667 at 1/250 dilution and ab195889 at 1/250 dilution (shown in pseudo colour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

  • Immunohistochemical analysis of Human Tonsil tissue labeling Ki-67 with ab16667 at 1:200. The HRP/AEC-staining procedure was used for detection.

  • ab16667 staining Ki67 in human testis by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue was fixed with formaldehyde and a heat mediated antigen retrieval step was performed using citrate buffer. Samples were then blocked with 1% B.S.A. for 10 minutes at 21ºC followed by incubation with the primary antibody for 2 hours at 1/100. A biotin-conjugated goat anti-rabbit polyclonal was used as secondary antibody at a 1/250 dilution.

  • ab16667 staining Ki67 (red) in transgenic mouse spinal cord tissue sections (depelted of oligodendrocytes) by Immunohistochemistry (PFA perfusion fixed frozen sections). Tissue samples were fixed by perfusion with paraformaldehyde, permeablized with 0.5% Triton X-100 and blocked with 10% serum for 1 hour at 25°C; antigen retrieval was by heat mediation in 10mM citrate buffer, pH 6, for 20 minutes at 97°C in a water bath. The sample was incubated with primary antibody (1/300 in PBS + 0.1% Triton X-100 + 1% serum) at 25°C for 16 hours. An Alexa Fluor® 594-conjugated donkey anti-rabbit IgG (H+L) polyclonal (1/700) was used as the secondary antibody. Counterstained with Iba1 (green) a marker for microglia and DAPI.
