Figure 1. IHC analysis of Ki67 using anti-Ki67 antibody (PB9026).Ki67 was detected in paraffin-embedded section of human tonsil tissues. Heat mediated antigen retrieval was performed in citrate buffer (pH6, epitope retrieval solution) for 20 mins. The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 1μg/ml rabbit anti-Ki67 Antibody (PB9026) overnight at 4°C. Biotinylated goat anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using Strepavidin-Biotin-Complex (SABC)(Catalog # SA1022) with DAB as the chromogen.
Figure 2. Western blot analysis of Ki67 using anti-Ki67 antibody (PB9026). Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 50ug of sample under reducing conditions. Lane 1: HELA Whole Cell Lysate,Lane 2: MCF-7 Whole Cell Lysate, Lane 3: COLO320 Whole Cell Lysate,Lane 4: HEPG2 Whole Cell Lysate,Lane 5: SKOV Whole Cell Lysate. After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA for 50-90 minutes. Blocked the membrane with 5% Non-fat Milk/ TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-Ki67 antigen affinity purified polyclonal antibody (Catalog # PB9026) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:10000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for Ki67 at approximately 358KD. The expected band size for Ki67 is at 358KD.
Figure 3. IF analysis using anti- Ki67 antibody (PB9026) detected in paraffin-embedded section of human colon organoid tissue. The tissue section were stained using the Dylight488-conjugated Anti-rabbit IgG Secondary Antibody (green)(Catalog#BA1127) and counterstained with DAPI (blue).
Figure 4. ICC analysis of KI67 using anti- KI67 antibody (PB9026).
KI67 was detected in an immunocytochemical section of Hela cells. Biotinylated goat anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The section was developed using Strepavidin-Biotin-Complex (SABC)(Catalog#SA1022) with DAB as the chromogen.
