Flow cytometry is continually expanding its applications as a research tool. Contact us to discuss what flow cytometry can do to help facilitate your research.Flow based technologies are tremendously useful for the analysis of cell cycle activity (by DNA content), proliferation (Ki67), stages of apoptosis Both these approaches to measuring proliferation by flow cytometry are extremely powerful taking a little care in sample preparation and being aware of some of the possible pitfalls will mean that your experiments will be more likely to work the first time! At AbD Serotec, we specialize in flow cytometry reagents and offer the largest range of antibody markers commercially available, together with accessory buffers. Our guiding principle is to manufacture products for use with every known flow cytometry instrument. The labeling indices (LI) of BrdUrd obtained Bromodeoxyuridine labeling index Flow cytometry both by flow cytometry (FCM) and immunohistochem- Tumor proliferation istry (IH) were also compared with the labeling index of Ki-67. 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.

Flow cytometric analysis of some activation/proliferation markers on human thymocytes. Neoplasma 46: 349-55.The proliferation antigen Ki67 and regulatory antigen CTLA-4 were assayed by flow cytometry on. The aim of this study was to investigate the prognostic value of cell proliferation (Ki-67 antigen) and DNA content in patients resected for distal bileMIB-1 antibody was used for Ki-67 antigen detection to determine the proportion of proliferating cells.
