Ki-67 Antibody (42-5699-82) in ICC/IF
Immunofluorescence analysis of Ki-67 Monoclonal Antibody (20Raj1), eFluor™ 615, eBioscience™ was performed using 70% confluent HeLa cells that were serum- starved (SS) for 36 hours followed by serum release (SR) for 6 hours. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with Ki-67 Monoclonal Antibody (20Raj1), eFluor™ 615, eBioscience™; (Product # 42-5699-82) at 1 µg/mL concentration in 0.... View More

Product Specific Information
Description: The monoclonal antibody 20Raj1 recognizes the human Ki-67 protein. Two isoforms of Ki-67 exist, a 345 and 395 kDa form that are expressed in dividing cells. Ki-67 is expressed in all cell types and is detectable during active phases of the cell cycle (G1, S, G2, and mitosis) but is absent from resting cells (G0). During interphase, Ki-67 expression is localized to the nucleus but redistributes to the chromosomes during mitosis and has specifically been found to associate with heterochromatin-bound proteins such as chromobox protein homolog 3 (CBX3). In studies of tumor cells, Ki-67 expression has been used as a marker for determining the fraction of proliferating cells within a given population of tumor cells.
This monoclonal antibody 20Raj1 recognizes canine Ki-67.
Applications Reported: This 20Raj1 antibody has been reported for use in immunocytochemical and immunohistochemical staining of paraffin-embedded tissue (IHC-P).
Applications Tested: This 20Raj1 antibody has been tested by immunocytochemistry on formaldehyde-fixed and permeabilized HeLa cells, and immunohistochemistry on FFPE human skin using low pH antigen retrieval. For immunocytochemistry and immunohistochemistry, this can be used at less than or equal to 1 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Filter Recommendation: When using this eFluor® 615 antibody conjugate, we recommend a filter that will capture the 615 emission wavelength. A standard Alexa Fluor® 594 filter is acceptable.
Excitation: 595 nm; Emission: 615 nm.
Filtration: 0.2 µm post-manufacturing filtered.
Target Information
Ki-67 is a nuclear protein that is expressed during various stages in the cell cycle, particularly during late G1, S, G2, and M phases. The protein has a forkhead associated domain (FHA) through which it associates with euchromatin at the perichromosomal layer, the centromeric heterochromatin, and the nucleolus. Ki-67 is shown to have a cell cycle dependent topographical distribution with perinucleolar expression at G1, expression in the nuclear matrix at G2, and expression on the chromosomes during M phase. Ki-67 is commonly used as a proliferation marker because it is not detected in G0 cells, but increases steadily from G1 through mitosis. Ki-67 antibodies are useful in establishing the cell growing fraction in neoplasms. In neoplastic tissues, the prognostic value is comparable to the tritiated thymidine-labelling index. The correlation between low Ki-67 index and histologically low-grade tumors is strong. Ki-67 is routinely used as a neuronal marker of cell cycling and proliferation.
