CD-Chex Select®

CD-Chex Select®

Positive Procedural Control for Immunophenotyping

CD-Chex Select is the first and only commercially available flow cytometry control with a selected group of CD markers used for immunophenotyping.

CD-Chex Select designed for use on BD Biosciences and Beckman Coulter® flow cytometry systems.

CD-Chex Select can be handled like a patient sample, which eliminates the need for laboratories to hold and validate patient samples to use as a control for the assayed markers.

Sample 1 provides % positive values for CD markers including CD26, CD41, CD57, CD64, FMC7, TCR α/β, TCR γ/δ. Sample 2 provides % positive values for epitopes CD58 and CD61 and intracellular markers CD79a and MPO.

CD-Chex Select is available in cap-pierceable plastic vials for use with automated sample preparation instruments. The plastic vial increases employee safety.

Streck offers STATS®, a free Interlaboratory Quality Control program for our customers.
