  1. aThe accuracy of recovery of three and six cells were done using GFP-expressing PDAC cells spiked into 5 mL of blood from healthy donors (n = 5). The number of cells used for spiking was visually confirmed before and after aspiration. Spiked samples were enriched for cancer cells using rVAR2-coated beads in combination with the IsoFlux™ and enumerated based on the detection of the GFP signal.
