Ki67/MKI67 Antibody (SR00-02)

Immunohistochemistry: Ki67/MKI67 Antibody (SR00-02) [NBP3-32498]

Immunohistochemistry: Ki67/MKI67 Antibody (SR00-02) [NBP3-32498] - Immunofluorescence analysis of paraffin-embedded human lymph nodes tissue labeling Ki67/MKI67 with Rabbit anti-Ki67/MKI67 antibody (NBP3-32498) at 1/500 dilution.

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 2 minutes. The tissues were blocked in 10% negative goat serum for 1 hour at room temperature, washed with PBS, and then probed with the primary antibody (NBP3-32498, green) at 1/500 dilution overnight at 4 ℃, washed with PBS.

Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. Nuclei were counterstained with DAPI (blue).

Immunohistochemistry: Ki67/MKI67 Antibody (SR00-02) [NBP3-32498] - Immunohistochemical analysis of paraffin-embedded human tonsil tissue with Rabbit anti-Ki67/MKI67 antibody (NBP3-32498) at 1/5,000 dilution.

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 2 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-32498) at 1/5,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunocytochemistry/ Immunofluorescence: Ki67/MKI67 Antibody (SR00-02) [NBP3-32498]

Immunocytochemistry/ Immunofluorescence: Ki67/MKI67 Antibody (SR00-02) [NBP3-32498] - Immunocytochemistry analysis of HeLa cells labeling Ki67/MKI67 with Rabbit anti-Ki67/MKI67/MKI67 antibody (NBP3-32498) at 1/100 dilution.

Cells were fixed in 100% precooled methanol for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-Ki67/MKI67 antibody (NBP3-32498) at 1/100 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.

Beta tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.

Background: Ki67/MKI67

Ki67 is a nuclear protein associated with proliferation, named after its discovery in a Hodgkin's lymphoma-derived cell line by Scholzer and Gerdes at Kiel University, Germany (1). This proliferation marker is expressed during active phases of the cell cycle (late G1, S, G2 and M), whereas the protein remains undetectable in the G0 phase. Ki67 has two main isoforms with theoretical molecular weights of 319 kDa and 359 kDa. Its abundance is tightly regulated by synthesis and degradation with an estimated half-life of 60-90 min, regardless of its position in the cell cycle. Ki67 has been shown to be involved in ribosomal biogenesis, heterochromatin maintenance, and mitotic chromosome separation (2).

Detection of Ki67 by immunostaining is commonly used as a proliferation marker in solid tumors, as well as certain hematological malignancies (3-5). The Ki67 index, which reports on positive Ki67 stained tumor cell nuclei, has been extensively studied as a prognostic biomarker in cancers such as breast cancer and cervical cancer.
