Product Description

CD-Chex Plus is a positive procedural control for monitoring immunophenotyping by flow cytometry. It provides 30 assayed parameters including T-lymphocytes, B-lymphocytes, granulocytes, monocytes and NK cells. It is available in two clinically relevant levels of CD4+ cells and is assayed for a normal level of CD34+ cells. Designed to resemble a patient sample, CD-Chex Plus is manufactured from normal human peripheral blood leukocytes and erythrocytes. The whole blood control offers 30-day open-vial stability, eliminating the need to track thermal openings. Its long shelf life reduces 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, reducing errors and improving laboratory workflow.

Based on Streck’s proprietary cell-stabilization technology, we offer a comprehensive line of positive procedural controls and cellular stabilization products for immunophenotyping by flow cytometry. Our unique quality controls provide assay values for both normal and abnormal leukocyte populations and reference values for both intracellular and surface markers. Our cellular stabilization products are designed to preserve samples for extended periods while easing handling concerns and allowing for room temperature storage, cold-chain free shipping and batch processing.
