CD-Chex CD34®

CD-Chex CD34 is the only commercially available three-level process control for enumerating CD34 positive cells by flow cytometry. It is an assayed, whole blood control that requires no dilution and provides reference values similar to levels found in bone marrow, cord blood and mobilized patient samples.

CD-Chex CD34 stem cell enumeration flow cytometry control

CD-Chex CD34 is a ready-to-use, positive procedural control for enumerating CD34 positive cells by flow cytometry. Designed to mimic a patient sample, CD-Chex CD34 contains human leukocytes and erythrocytes in a preservative medium with CD34 positive cells having characteristics similar to human hematopoietic progenitor cells. The whole blood control does not need to be diluted and offers 30-day open-vial stability, eliminating the need to track thermal openings. Its long shelf life reduces the number of shipments, associated costs and time spent performing lot-to-lot correlation.
