Laser flow cytometry and cancer chemotherapy: detection of intracellular anthracyclines by flow cytometry.

The intracellular distribution of important chemotherapeutic antibiotics belonging to the anthracycline group (e.g. adriamycin) can be detected by laser flow cytometry. The indirect method is based on the interference of these compounds with the binding of propidium iodide to the nuclear DNA. While in the direct method, the intracellular fluorescence of these antibiotics is excited and detected with a laser beam in a flow system. The present report demonstrates the use of these two methods for intracellular detection and quantitation of a number of important anthracyclines.

Flow Cytometry: Long-Term Storage of Propidium Iodide/Citrate-Stained Material

Single cell suspensions stained by the propidium iodide/hypotonic citrate method for DNA content analysis by flow cytometry can be mixed with an equal amount of 70% alcohol for long-term storage and shipping without introduction of artifacts or loss of fluorescence.
