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 immunophenotyping quality control for flow cytometry

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.
