In biotechnology, flow cytometry is a laser- or impedance-based, biophysical technology employed in cell counting, cell sorting, biomarker detection and protein engineering, by suspending cells in a stream of fluid and passing them through an electronic detection apparatus. Turk J Immunol, 1999 4:S 66-67. A.
ntigen-specific T-cell proliferation is frequently used as an assay for measuring T-cell responses.After incubation for 45 min. at room temperature, cells are washed, resuspended in PBS and analyzed by two-color flow cytometry. The method of DNA/Ki-67 double staining of solid tissue and cultured cells for flow cytometry is shownThe proliferative activity of gastric cancer cells was determined by DNA flow cytometric (FCM) analysis and labeling rates of Ki-67 and monoclonal antibodies and proliferation-associated The proliferative activity of various parts of normal and malignant endometrium was evaluated using an immunohistochemical approach and flow cytometry (FCM). The two monoclonal antibodies, Ki-67 and anti-DNA polymerase alpha antibody (anti-poly alpha antibody) Cellular proliferation assessment with Ki-67 measures a tumor-growth parameter that is distinct from both PCNA and flow cytometry (57). Two antibodies against the Ki-67 protein, the Ki-67 antibody and MIB-1, are available for use in immunohis-tochemical assays.
