CD-Chex Select is a positive procedural control that includes CD26, CD41, CD57, CD58, CD61, CD64, CD79a, FMC7, MPO, TCR α/β and TCR γ/δ. It is an assayed, whole blood control that features a cap pierceable vial for use with automated flow cytometry sample preparation instruments.
Product Description
Designed to mimic a patient sample, CD-Chex Select contains human leukocytes and erythrocytes in a preservative medium. The cells in CD-Chex Select possess surface and intracellular antigens detectable with fluorescent monoclonal antibodies by flow cytometry. It 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 is designed to represent normal peripheral blood leukocytes where lymphocytes, monocytes, and granulocytes are distinguishable on the basis of light scatter properties.
For Research Use Only. Not for use in diagnostic procedures.
