CD-Chex TdT Plus is the only commercially available flow cytometry control that includes TdT, CD1a, CD34 and cCD3 in a single control. It is a positive procedural control that provides reference values for abnormal cells often found in certain types of hematopoietic neoplasms.
Product Description
CD-Chex TdT Plus is a ready-to-use control for evaluating intracellular and surface antigens including CD1a, CD2, CD4, CD5, CD7, CD8, CD34, cytoplasmic CD3 and nuclear TdT, with monoclonal antibody binding by flow cytometry. When the cells are stained with fluorescent antibodies and analyzed by flow cytometry, CD-Chex TdT Plus provides reference values for abnormal peripheral blood leukocytes often found in certain types of hematopoietic neoplasms.
For Research Use Only. Not for use in diagnostic procedures.
Features
- Only flow cytometry control assayed for TdT, CD1a, CD34 and cytoplasmic CD3
- Other assayed markers include CD2, CD4, CD5, CD7 and CD8
- Offers a high level of CD34: over 60% positive for CD34+ (abnormal)
- Compatible with BD Biosciences and Beckman Coulter flow cytometry systems
- 30-day open-vial stability
- 90-day closed-vial stability
Benefits
- Helps toward meeting quality requirements for leukemia and lymphoma immunophenotyping
- Helps technologists to identify and gate assayed markers
- Established assay ranges provide less room for error
- Reduces the need for labs to hold and validate patient samples for use as a control
- Access to STATS®, a free interlaboratory quality control program with peer group data comparison and online submission
