CytoQuest™ CR - Circulating Rare Cell Positive Enrichment & Retrieval System

Abnova’s CytoQuest™ CR is a non-invasive system for capture, enumeration, isolation and retrieval of circulating rare cells (CRCs). Three major subtypes of CRCs in translational research and clinical studies are circulating tumor cells (CTCs), circulating progenitor cells (CPCs), and circulating fetal cells (CFCs). A challenge for market adoption of CRCs is the efficient and reproducible identification, single cell isolation, and retrieval of highly pure and viable CRCs, with their applications supported by a wide repertoire of standardized, GMP grade bioreagents.

CytoQuest™ CR technology utilizes SCx™ spiral chamber, HBx™ micromixer, antibody immobilized nanoarray, and TCx™ thermal control to enable a multitude of CRC functions. SCx™ spiral chamber is equipped with a non-sticky coil and a self-contained micro-vibrator for unimpeded delivery of pretreated blood sample into the nanoarray. HBx™ micromixer provides a herringbone conduit for cell mixing. CytoChipNano is a streptavidin nanoarray which captures the CRCs for cell enumeration and single cell isolation by laser microdissection or micromanipulation. CytoChipNano CR is a specialized streptavidin nanoarray with thermo-sensitive coating which captures and releases the CRCs via a TCx™ thermal control of alternating temperatures.

Monoclonal antibodies targeting specific surface biomarkers of circulating rare cells can be flexibly interchanged to accommodate the biomarker switch in CRC progression. This results in highly pure and viable CRCs for downstream protein characterizations, gene analysis, and cell assays. Cell enumeration is currently the only FDA approved application as a prognostic marker in breast, prostate, and colorectal cancers. In contrast, effective single cell isolation and retrieval of CRCs opens up new scope of applications in the diagnostic and pharmaceutical industry.
