CD-Chex CD117 Plus is a ready-to-use control for evaluating CD117, CD25 and CD71 expression by flow cytometry. Developed to resemble peripheral blood leukocytes often found in a hematolymphoid neoplastic patient sample, CD-Chex CD117 provides percent-positive values for CD117, CD25 and CD71 on abnormal and total leukocytes. Abnormal leukocytes are distinguishable from normal leukocytes based on light scatter properties and low CD45 expression. 

CD-Chex CD117 is a positive procedural control designed to monitor reagent staining, erythrocyte lysis, sample preparation and instrument performance and is compatible with BD® Biosciences and Beckman Coulter® flow cytometry systems.
