Assayed control.

CD-Chex Plus BC is an assayed control for immunophenotyping with flow-cytometry systems. CD-Chex Plus BC determines the accuracy and reproducibility of all the steps involved in the process of immunophenotyping, including red-blood-cell lysis. Reference values for five subsets of leukocytes include T lymphocytes, B lymphocytes, granulocytes, monocytes, and NK cells. CD-Chex Plus BC CD4 Low offers a depressed CD4 absolute number often indicated in patients with immunodeficiency diseases. CD-Chex Plus BC and CD-Chex Plus BC CD4 Low products offer 30-day open-vial stability and 90-day closed-vial stability. Both are available in plastic vials with pierceable caps containing a 3.0-mL fill.
