CD-Chex TdT Plus®
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.
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.

Quality Pillars for Building Measurement Assurance in Flow Cytometry
The webinar provides updates on the current best quality practices in flow cytometry and case studies for assay, reagent and instrument monitoring.
Flow Cytometry Products
Based on Streck’s proprietary cell-stabilization technology, we offer a comprehensive line of positive procedural controls and cellular stabilization products for immunophenotyping by flow cytometry. Our unique quality controls provide assay values for both normal and abnormal leukocyte populations and reference values for both intracellular and surface markers. Our cellular stabilization products are designed to preserve samples for extended periods while easing handling concerns and allowing for room temperature storage, cold-chain free shipping and batch processing.
