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.

For Research Use Only. Not for use in diagnostic procedures.
