  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Ki67 antibody [EPR3610] (ab92742)

  Comparison between RNApII-S2P-/low cells and Ki-67- cells
  

  a: Regulation of Ki-67 and RNApII-S2P during proliferation and quiescence in T98G glioblastoma cells. T98G cells were grown in culture medium containing 10% (v/v) fetal bovine serum (FBS), were induced to become quiescent by serum starvation in medium supplemented with 0.5% (v/v) FBS for 14 days, and then were re-stimulated by being split 1:5 into new medium containing 10% (v/v) FBS and cultured for 3 days. The cells were detached from dishes with trypsin-EDTA solution, fixed in 10% (v/v) neutral buffered formalin, and centrifuged. Paraffin sections of the pellet were cut, and expression of Ki-67 and RNApII-S2P was examined by single (brown; a1, a2, a4, a5, a7, a8) or double immunostaining (Ki-67, brown; RNApII-S2P, red; a3, a6, a9). Hematoxylin (blue) was used as a nuclear stain. Ki-67- RNApII-S2P-/low cells (blue cells in the double stained sections) emerged only in the quiescent condition (a6, arrows). Scale bar, 10 μm. b: Single-color immunostaining for Ki-67 (b1) and RNApII-S2P (b2) in serial sections of glioblastoma tissue. Ki-67- tumor cells were frequently found, whereas only a few RNApII-S2P-/low cells (arrows) were observed around necrotic area. N, necrotic area; V, blood vessels. Scale bars, 50 μm.

  Panel e:ER⁺ PgR^- Ki-67^- cells were stained red (short arrow), ER^- PgR⁺ Ki-67^- cells were stained blue (black arrowhead), ER⁺ PgR⁺ Ki-67^- cells were stained purple (long arrow), and Ki-67⁺ cells were stained brown (white arrowhead). These colors are easily distinguishable. Scale bars, 25 μm.

  Deparaffinized sections were pretreated for antigen retrieval by boiling in antigen retrieval solution, pH 9. Sections were incubated with rabbit monoclonal antibody against Ki67 ab92742 at a 1/1000 dilution. After the reaction with (HRP)-conjugated secondary antibodies color was developed with (DAB) and sections were counterstained with hematoxylin.

To generate this image, wild-type and MKI67 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.
