Blessin, N.C. et al. stated that Ki67 can rapidly and reproducibly be analyzed by AI-supported multiplex fluorescence IHC (mfIHC), with the major advantage of strict limitation of the analysis to tumor cells, which cannot be achieved in ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) based panel analyses [98]. The gene discussed is MKI67; the disease is neoplasm.
