Normal Whole blood control for Flow cytometry immunophenotyping, CD-Chex Plus® controls a wide range of CD markers, Streck 5 x 3ml

Immunophenotyping by flow cytometry provides a rapid and accurate assessment of the frequency and type of leukocytes present in a whole blood sample. Quantitation of peripheral blood leukocyte subsets has been shown to be useful in the evaluation of immunodeficiency, autoimmune, and oncologic disorders.

CD-Chex Plus is a whole blood positive procedure control with assayed values used to monitor:
reagent staining
erythrocyte lysis
sample preparation
instrument performance

CD-Chex Plus control cells mimic whole blood samples by possessing surface antigens detectable with fluorescent monoclonal antibodies by flow cytometry.

Positive Procedural Control for Immunophenotyping
CD-Chex Plus® is a positive procedural control for monitoring immunophenotyping by flow cytometry. It provides the most assayed CD markers in the industry on a single control, including those on the HIV panel of markers recommended by the CDC and a normal level of CD34+ cells. CD-Chex Plus is manufactured from normal human peripheral blood leukocytes and erythrocytes. Available in two clinically relevant levels of CD4+ cells.

Compatible with most popular flow cytometry systems.

CD-Chex Plus verifies the accuracy and reproducibility of the steps involved in the process of immunophenotyping, including:
• Verification of mAb reagents
• Validation of instrument performance
• Validation of operator technique
• Verification of red blood cell lysis
