PA1-21520 detects Ki67 in human, mouse, and rat samples.
PA1-21520 has been successfully used in immunohistochemistry (paraffin) and ICC/IF procedures. Staining of formalin/paraffin tissues requires boiling tissue sections in 10 mM citrate buffer, pH6.0, for 10-20 minutes, followed by coolong at room temperature for 20 minutes.
The PA1-21520 immunogen is a synthetic peptide from the human Ki-67 antigen. PA1-21520 recognizes an epiptope in the middle of the Ki67 protein.
Ki-67 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 (immunohistochemically quantified by determining the number of Ki67-positive cells among the total number of resting cells = Ki67 index). In neoplastic tissues the prognostic value is comparable to the tritiated thymidine-labelling index. The correlation between low Ki67 index and histologically low-grade tumours is strong.
