Flow Cytometry

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 CD-Chex^® 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.
