Flow cytometry is only as good as the sample it sees.

Between collection and acquisition, platelet and leukocyte samples change. Platelets activate spontaneously ex vivo, and leukocyte surface antigens degrade during transport, processing delays, and batching. The sooner a sample is stabilized after collection, the more accurately it reflects the donor's state at the time of collection.

IntelliFlow™ stabilizes samples post-collection: up to 7 days at room temperature or 2–8°C for the Platelet Stabilization Tube (PST, CD62P), and up to 22 days for the Leukocyte Stabilization Tube (LST, lymphocyte subsets).

IntelliFlow™ stabilization products are supplied pre-filled and ready to use — no reagent preparation required.
