Expression of Ki-67 appears to be limited to the activity phases of the cell-cycle (1, 2). Ki-67 is expressed in G1, G2, S and M phases but is absent in G0 or resting phase. As a proliferation marker, Ki-67 has both diagnostic and prognostic value for a metricized analysis (1-3). The Ki-67 growth fraction or Ki-67 GF has been used in a variety of cancers but especially breast cancer populations3. For example, Ki-67 criteria can be correlated to different other prognostic parameters such as tumor stage, hormone receptor status, patient age (4). Antibody to Ki-67 therefore allows analysis of positive-expressing cells in treatment regimen as well as for prognosis by IHC and Flow Cytometry as routine key platforms.
