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.
Product Description
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.
Features
- Only commercially available CD34 control with three levels
- Ready to use control; no dilution required
- Whole blood control mimics patient sample
- Compatible with flow cytometers using 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 and associated costs
- Established assay ranges provide less room for error
- Tests a wider range of CD34 enumeration not offered by alternative controls
- Fewer lot-to-lot correlations save time and resources

的病例和经 PBPC 输入治疗了难治性骨髓瘤患者，发现以上因素使自体移植中 CD34+ 细胞的最佳剂量各不相同。此研究表明，对于移植前接受化疗少于 24 个月的病人，快速植活剂量应 >2.0 X 106 CD34+ 细胞 /kg ；对于长期接受全身化疗的病人（大于 24 人月）最低剂量则为 >5.0 X 106 CD34+ 细胞 /kg 。此处接受短期化疗的病人更容易、快速地取得 CD34+ 细胞。总而言之，这些研究表达 2-5 X 106 CD34+ 细胞 /kg 的剂量对于大多数情况下是足够
