Great control for clinical stem cell evaluation.
Rating: 5.0

  • Application Area: Clinical stem cell quantitation/analysis

"A great control for stem cell evaluation/quantitation. Have been using this product clinically for over 10+ years and results always fall within the desired range. Sales rep is great and checks in regularly. They do standing orders to ensure you get your product when you need it."

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.

CD-Chex CD34 is compatible with flow cytometry systems using ISHAGE gating strategies for enumeration of CD34 cells and these commercially available enumeration kits: BD Biosciences ProCOUNT Progenitor Cell Enumeration Kit, BD Stem Cell Enumeration Kit and Beckman Coulter Stem-Kit. It is the only stem cell control for CD34+ positive cells that offers three levels.
