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.
CD-Chex CD34 is compatible with flow cytometry systems using ISHAGE gating strategies for enumeration of CD34 cells and for the following commercially available enumeration kits: BD® Biosciences ProCOUNT™ Progenitor Cell Enumeration Kit, BD Stem Cell Enumeration Kit and Beckman Coulter® Stem-Kit.
Features
- Only commercially available CD34 control with three levels
- No dilution required
- Whole blood control- resembles patient sample
- Compatible with flow cytometers using the ISHAGE protocol and enumeration kits
- 30-day open-vial stability; 90-day closed-vial stability
Benefits
- Helps clinical laboratories meet quality requirements for CD34+ stem cell quantitation
- Long shelf life reduces the number of shipments, associated costs and lot-to-lot correlations
- Manufacturer established assay ranges – no need to verify range per CAP requirements
- Access to STATS®, Streck’s free interlaboratory quality control program for peer group data comparison
