Winner of the SLAS 2019 New Product Award!

A step forward in characterization capabilities within the extracellular vesicles (EV) field. The fully automated platform provides multi-level and comprehensive EV measurements for particle size analysis, EV count, EV phenotype, and biomarker colocalization. The ExoView™ platform provides previously unattainable information in a single and bias free sample workflow.

ExoView™ works without the need for sample purification, and brings the researcher one step closer to analyzing a sample in its natural state. ExoView™ R100 is an affinity based technology that allows specific populations of EVs to bind in a multiplexed manner to a functional ExoView™ chip. The fully automated instrument can measure 9 samples automatically, direct from sample, saving cost, time, and reducing purification biases.

ExoView™ R100 Key Features:



3 color fluorescence. Single binding event sensitivities mean that even the smallest EVs are detectable

Probe for EV luminal proteins and cargo



Measure up to 4 markers on single EVs:

The ExoView™ platform provides the ability to measure up to 4 markers on single EVs. The multiplexed array allows up to 6 markers to be probed in parallel through binding of the EVs to an ExoView™ chip. The addition of fluorescent antibodies provides the ability to probe for an additional 3 markers with single fluorescent antibody sensitivity.

The image shows the binding of single EVs to a CD9 antibody spot, interferometric imaging measurements are shown to the left and 3 color fluorescence on the right. A heat map of marker expression on single EVs can be generated (external or luminal proteins), while simultaneously measuring their size and count.
