    Total cell lysates (15 µg protein) from Raw264.7 and NIH3T3 were resolved by 3-8% Tris-Acetate gel electrophoresis, transferred to nitrocellulose, and probed with mouse Ki-67 antibody (clone 16A8). Proteins were visualized using a goat anti-rat IgG secondary antibody conjugated to HRP and chemiluminescence detection. Direct-Blot™ HRP anti-β-actin was used as a loading control.

    TE‐71 cells were fixed with 1% paraformaldehyde (PFA) for ten minutes, permeabilized with 0.5% Triton X‐100 for ten minutes, and blocked with 5% FBS for 30 minutes. Then the cells were intracellularly stained with 2.5 μg/mL of purified Ki‐67 (clone 16A8) in 5% FBS overnight at 4°C, followed by Alexa Fluor® 647 goat anti-rat IgG (clone Poly4054, red) for two hours. Nuclei were counterstained with DAPI (blue). The image was captured with a 40X objective.

    C57BL/6 mouse frozen intestine section was fixed with 4% paraformaldehyde (PFA) for ten minutes, permeabilized with 0.5% Triton X-100 for ten minutes, and blocked with 5% FBS plus 5% goat serum for 30 minutes at room temperature. Then the section was stained with 5 µg/mL purified Ki-67 (clone 16A8) in 5% FBS overnight at 4°C, followed by Alexa Fluor® 647 goat anti-rat IgG (clone Poly4054, red). Nuclei were counterstained with DAPI (blue). The image was captured with a 10X objective.

Description

The nuclear protein Ki-67 was first identified by the monoclonal antibody Ki-67, which was generated by immunizing mice with nuclei of the L428 Hodgkin lymphoma cell line. Ki-67 protein plays an essential role in ribosomal RNA transcription and cell proliferation. Expression of Ki-67 occurs during G1, S, G2, and M phase, while in G0 phase the Ki-67 protein is not detectable. Ki-67 is strongly expressed in proliferating cells and has been reported as a prognostic marker in various tumors.

Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µl volume. For western blotting, suggested working dilution(s): Use 5 µl per 5 ml antibody dilution buffer for each mini-gel (0.5 µg/ml). For immunocytochemistry, a concentration range of 1.25 - 5.0 μg/mL is recommended. For immunohistochemistry on frozen tissue sections, a concentration range of 2.5 - 10.0 µg/mL is suggested. Additionally, each lot of this antibody is quality control tested by our Ki-67 staining protocol below. It is recommended that the reagent be titrated for optimal performance for each application.
