RE: CTCs versus Circulating DNA30 Mar 2023 17:52
My point is that AN views ctDNA & CTC analysis as complementary to each other.
They have designed a workflow that “allows combining CTC isolation using the Parsortix® system with plasma removal for subsequent ctDNA analysis from a single tube of blood, opening the possibility for clinical laboratories to broaden the potential clinical utility of their assays and limiting the overall blood volume requirement.”
The “subsequent ctDNA analysis” would be performed by a third party platform. “This opens the possibility for clinical laboratories to broaden the clinical utility of their assays and maximise the value of each patient's sample. Despite the emerging realisation of the benefit of a combinatorial approach to blood analysis, the logistics revolving around access to both a CTC enrichment platform and a ctDNA sequencing platform at the same site has so far limited such analysis. ANGLE believes there will be significant demand from biopharma companies for an assay that combines ctDNA and CTCs. The workflow presented, demonstrating effective CTC isolation utilising the Parsortix system with concurrent removal of plasma for ctDNA analysis, puts ANGLE in a highly competitive position in this emerging arena.”
