Product Description

CD-Chex CD34 is a ready-to-use, positive procedural control for enumerating CD34 positive cells by flow cytometry. Designed to resemble a patient sample, CD-Chex CD34 contains human leukocytes, erythrocytes and CD34 positive cells with characteristics similar to human hematopoietic progenitor cells. This control does not require any dilution and offers 30-day open-vial stability, which eliminates the need to track thermal openings, and 90-day closed-vial stability, reducing the number of shipments, associated costs and time spent performing lot-to-lot correlation…
