title: Principles and applications of flow cytometry and cell sorting in companion animal medicine.
abstract: Flow cytometry measures multiple characteristic of single cells using light scatter properties and fluorescence properties of fluorescent probes with specificity to cellular constituents. The use of flow cytometry in the veterinary clinical laboratory has become more routine in veterinary diagnostic laboratories and institutions (http://www.vet.k-state.edu/depts/dmp/service/immunology/index.htm), and reference laboratories. The most common applications in small animal medicine includes quantitation of erythrocytes and leukocytes in automated hematology instruments, detection of antibodies to erythrocytes and platelets in cases of immune-mediated diseases, immunophenotyping of leukocytes and lymphocytes in immunodeficiency syndromes, or leukemias and lymphomas. DNA content analysis to identify aneuploidy or replicating cells in tumor preparations has not gained routine acceptance because of the variability of prognostic results. Other applications including cell sorting and multiplexing using microspheres are potential assays of the future once they become validated and the instrumentation footprint becomes more and more compact, less expensive, and easier to use.
