Angle Portrait Flex CTC Assay

Angle said this week that it has launched the Portrait Flex CTC assay as a service provided by its Onc-ADaPT GCP-compliant laboratories. The Flex test uses immunofluorescence staining for epithelial, mesenchymal, blood lineage, and nuclear markers on cells isolated with its Parsortix system, with the opportunity to include additional biomarkers tailored to customer needs. Angle claims an analytical sensitivity of more than 93 percent and an analytical specificity of over 95 percent for both epithelial and mesenchymal markers.
