Normal and CD4 Low Whole blood control optimised for Beckman Coulter Flow cytometers, CD-Chex Plus® BC Streck 4 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, and 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® BC 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 BC is manufactured from normal human peripheral blood leukocytes and erythrocytes. Available in two clinically relevant levels of CD4+ cells

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

Compatible with Beckman Coulter­® flow cytometry systems

3.0ml cap-pierceable plastic vials.
