Polyclonal Rabbit Affinity Purified IH IC IF
Ki67 antigen is the prototypic cell cycle related nuclear protein, expressed by proliferating cells in all phases of the active cell cycle (G1, S, G2 and M phase). It is absent in resting (G0) cells. Ki67 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 Ki67 index and histologically low-grade tumors is strong. Ki67 is routinely used as a neuronal marker of cell cycling and proliferation.
Catalog #K1700-10F
ApplicationsSuitable for use in Immunohistochemistry, Immunocytochemistry and Immunofluorescence. Other applications not tested.
Recommended DilutionsImmunohistochemistry (Frozen/Paraffin): 1:50-1:300 Formalin-fixed paraffin-embedded tissue sections require high temperature antigen unmasking with 10mM citrate buffer, pH 6.0 prior to immunostaining. Will not work without optimal antigen retrieval. An incubation period of 30 minutes at RT and the use DAB to stain the protein (immunofluorescence may give problems as the protein is nuclear) is suggested.
Immunocytochemistry: 1:50
Immunofluorescence: 1:20
Optimal dilutions to be determined by the researcher.
Positive ControlTonsil
