CD-Chex CD117® Plus

CD-Chex CD117 Plus is a flow cytometry control that provides assay values for CD117, CD25 and CD71 on abnormal and total leukocytes.

CD-Chex-CD117 Plus

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.
