CD-Chex Plus®

CD-Chex Plus®

CD-Chex Plus is a positive procedural control for T-lymphocyte, B-lymphocyte and NK cell enumeration and features two clinically relevant levels of CD4+ cells, a normal level of CD34+ cells and several other parameters for use as leukemia and lymphoma quality controls.

CD-Chex Plus provides 30 assayed parameters for immunophenotyping by flow cytometry including T-lymphocytes, B-lymphocytes and NK cells. It is available in two clinically relevant levels of CD4+ cells and features a CD34+ population and several additional parameters that can be used as leukemia and lymphoma quality controls…

…Designed to resemble a patient sample, CD-Chex Plus is manufactured from normal human peripheral blood leukocytes and erythrocytes and can be used to verify the accuracy and reproducibility of the steps involved in the process of the immunophenotyping including reagent staining, erythrocyte lysis, sample preparation, and instrument performance. This control offers 30-day open-vial stability, which eliminates the need to track thermal openings, and 90-day closed-vial stability, reducing the number of shipments, associated costs and time spent performing lot-to-lot correlation.

CD-Chex Plus and CD-Chex Plus CD4 Low are available in plastic vials with pierceable caps for use with automated flow cytometry sample preparation instruments and are assayed for immunophenotyping with BD® Biosciences and Beckman Coulter® flow cytometry systems.
