CD-Chex Select is a positive procedural flow cytometry control assayed for 11 CD markers used for immunophenotyping: CD26, CD41, CD57, CD58, CD61, CD64, FMC7, TCR α/β, TCR γ/δ, and intracellular CD79a and MPO. CD-Chex Select contains human leukocytes and erythrocytes that possess surface and intracellular antigens detectable with fluorescent monoclonal antibodies by flow cytometry and is designed to represent normal peripheral blood leukocytes where lymphocytes, monocytes, and granulocytes are distinguishable on the basis of light scatter properties. Designed to resemble a patient sample, this control monitors reagent staining, erythrocyte lysis, sample preparation and instrument performance.
