CD-Chex TdT Plus is the only commercially available flow cytometry control assayed for TdT, CD1a, CD34 and cCD3 in a single control. The assay provides percent positive values for each assayed marker on abnormal leukocytes.

CD‑Chex TdT Plus can be used as quality control material for evaluating intracellular and surface antigens including CD1a, CD2, CD4, CD5, CD7, CD8, CD34, cytoplasmic CD3 and nuclear TdT (Terminal deoxynucleotidyl transferase). When stained with fluorescent antibodies and analyzed by flow cytometry, CD‑Chex TdT Plus provides reference values for abnormal cells often found in certain types of hematopoietic neoplasms.
