We have developed a multi-parametric high-throughput flow-based method for the analysis and sorting of individual extracelluar vesicles (EVs), which are highly heterogeneous and comprise a diverse set of surface protein markers as well as intra-vesicular cargoes. Yet, current approaches to the study of EVs lack the necessary sensitivity and precision to fully characterize and understand the make-up and the distribution of various EV subpopulations that may be present. In fact, most current EV isolation methodologies, including differential centrifugation, affinity/immuno-magnetic isolation, polymer-based precipitation, size-based exclusion, can be prone to contaminations and cannot resolve single EVs. Our new technology platform is able to immune-phenotype EVs and quantify proteins associated with EVs, at the single-EV level, with high precision and throughput.

High-Purity and High-Sensitivity Rare-Cell Isolation with Aliquot Sorting

Monday, 13 December 2021 at 16:30

This presentation describes the high-sensitivity isolation of rare cells, including circulating tumor cells and fetal cells, using fluorescence activated aliquot sorting. Here, a blood sample is divided into nanoliter volumes or aliquots, then analyzed and sorted based on the presence or absence of a rare cell. By performing two rapid, on the millisecond timescale, back-to-back sorting, we also demonstrate isolation of rare cells with high purity. Finally, we drastically increased the number of nucleated cells sorted by first concentrating peripheral blood mononuclear cells from whole blood, which translated into an equivalent blood volume analyzed by over an order of magnitude, from 8mL to over 100mL per experiment.
