CD-Chex Daily is a stabilized whole blood flow cytometry control delivering 51 assayed RUO markers in a single vial. Designed for modern immunophenotyping workflows, CD-Chex Daily consolidates daily QC into one streamlined run- reducing tech time, antibody use and setup complexity.
For Research Use Only. Not for use in diagnostic procedures.
51 assayed RUO markers in a single vial — 44 surface markers, 4 intracellular markers and 3 leukocyte scatter populations, including markers not previously available in any commercial flow cytometry control (CD27, CD28, TRBC1, CD79b, CD81, CD45RA, CD45RO, CD36, CD24, IgM)*
*See our entire marker list here.
Stabilized whole blood matrix challenges the complete analytical workflow — antibody staining, RBC lysis, acquisition and analysis
Manufacturer-established assay ranges — CAP, CLIA, CLSI and ISO 15189-compliant
30-day open-vial stability; 90-day closed-vial stability
Single vial replaces multiple QC runs, reducing reagent use, tube setups and hands-on preparation time
Manufacturer-established assay ranges eliminate the need to independently verify ranges for qualitative testing, consistent with CAP FLO.23925 & ISO 15189
Reduces reliance on donor-sourced, fragmented in-house QC
Access to STATS®, our free interlaboratory QC program for peer group comparisons

CD-Chex Daily is a stabilized whole blood flow cytometry control delivering 51 assayed RUO markers in a single vial. Designed for modern immunophenotyping workflows, CD-Chex Daily consolidates daily quality control into one streamlined run, reducing tech time, antibody use and setup complexity.
CD-Chex Plus is an FDA-cleared quantitative control designed for clinical use in T-lymphocyte, B-lymphocyte and NK cell enumeration. CD-Chex Daily is a Research Use Only qualitative control with 51 assayed RUO markers designed for modern immunophenotyping workflows.
CD-Chex Daily is designed to cover the most commonly used immunophenotyping markers in flow cytometry workflows. If a specific marker needed for your panel is not included in the 51 assayed markers, please contact our flow cytometry specialists.
Qualitative QC verifies that markers can be correctly identified as positive or negative, confirming that the instrument and reagents can detect the presence or absence of antigens. Quantitative QC verifies the accuracy of cell counts or percentages, confirming precise numerical measurements. CD-Chex Daily is ideal for immunophenotyping workflows where marker identification is the primary goal.
Many research laboratories use donor-sourced blood or retained patient samples for flow cytometry quality control, which requires ongoing recruitment, validation and management of specimen inventory. CD-Chex Daily provides a ready-to-use commercial control with manufacturer-established assay ranges and comprehensive marker coverage, eliminating the need for fragmented in-house QC programs and reducing the logistical burden of maintaining donor-sourced controls.
For qualitative testing, CD-Chex Daily provides manufacturer-established assay ranges that eliminate the need to independently verify ranges, consistent with CAP FLO.23925 and ISO 15189 requirements. This saves time and resources while ensuring compliance with regulatory standards for flow cytometry quality control.
