29593-1
LaboratoryCells.Ki-67 nuclear Ag/cells in Tissue by Immune stain
Definition
Ki-67 is a proliferation marker that correlates with flow cytometric S-phase. Breast cancer specimens with greater than 20% Ki-67 positivity will generally have a high S-phase fraction, which is an unfavorable prognostic marker.
