  Secondary antibody used was HRP BOND Refine Detection kit. Blocking was done with 5% serum for 1 hour at 20 °C. The sample was incubated with the primary antibody for 18 hours at 4°C with 1% BSA. Antigen retrieval method was heat mediated 10mm sodium citric buffer, PH 6

  Western blot - Anti-Ki67 antibody [SP6] (ab16667)

  Western blot: Anti-MKI67 antibody [SP6] (ab16667) staining at 1/500 dilution, shown in green; Mouse anti-CANX [CANX/1543] (Anti-Calnexin antibody [CANX/1543] ab238078) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab16667 was shown to bind specifically to MKI67. A band was observed at 359 kDa in wild-type A549 cell lysates with no signal observed at this size in MKI67 knockout cell line. 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.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Ki67 antibody [SP6] (ab16667)

  Tissue Microarrays stained for "Anti-Ki67 antibody [SP6]” using "ab16667" at 1/200 dilution (0.145 μg/ml) in immunohistochemical analysis. This table provides a detailed overview of positive (tick mark) and negative (cross mark) staining per sample type tested. Taking human colon tissue as an example, Ki67 is barely expressed or the expression level is very low in normal colon tissue, and the IHC test result is usually negative. While the expression of Ki67 can be upregulated in the proliferating cells of colon tissue, and the IHC test result could be positive.
  The sections were pre-treated using Heat mediated antigen retrieval using Antigen Retrieval Buffer (100X Citrate Buffer) ab93678 (citrate buffer, pH 6.0). The sections were incubated with ab16667 at +4°C overnight followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP polymer) (Goat Anti-Rabbit IgG H&L (HRP polymer) ab214880). Hematoxylin was used as the counter stain.

  Ki67 immunohistochemistry staining of human tonsil using rabbit anti-Ki67 antibody
  
  Immunohistochemical analysis of formalin fixed paraffin embedded human tonsil labelling Ki67 with ab16667 at 1/500 dilution. The immunostaining was performed on a Ventana DISCOVERY ULTRA (Roche Tissue Diagnostics) instrument with an OptiView DAB IHC Detection Kit. Heat mediated antigen retrieval was conducted for 32min with ULTRA cell conditioning solution (CC1 pH8.5). ab16667 anti Ki67 antibody was incubated at 37°C for 16min. Sections were counterstained is with Hematoxylin II. Image inset shows absence of staining in secondary antibody only control.
