CD-Chex CD34 is an FDA-cleared positive procedural control for enumerating CD34 positive cells by flow cytometry. It requires no dilution and provides reference values similar to levels found in bone marrow, cord blood and mobilized patient samples.
Product Description
CD-Chex CD34 is a ready-to-use, FDA-cleared 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…
