CD-Chex CD117® Plus

CD-Chex CD117 Plus is the only commercially available flow cytometry control that includes CD117, CD25 and CD71. It is a positive procedural control that provides assay values for abnormal and total leukocytes.

CD-Chex CD117 Plus immunophenotyping quality control for flow cytometry

CD-Chex CD117 Plus is a ready-to-use control for evaluating surface antigens, including CD117, CD25, and CD71, with monoclonal antibody binding by flow cytometry. It was developed with characteristics similar to abnormal peripheral blood leukocytes often found in a hematolymphoid neoplastic patient sample. The assay provides percent-positive values for CD117, CD25 and CD71 on abnormal and total leukocytes. Abnormal leukocytes are distinguishable from normal leukocytes on the basis of light scatter properties and a low level of CD45 expression.

Quality Pillars for Building Measurement Assurance in Flow Cytometry

The webinar provides updates on the current best quality practices in flow cytometry and case studies for assay, reagent and instrument monitoring.

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.
