Silicon Microsieve Device vs Cell Surface Marker-based Platform for the Isolation of Pancreatic Cancer CTCs

Both portal venous and peripheral blood will be processed through a label-free size-based silicon microsieve microfiltration device, which will isolate both epithelial-type and mesenchymal-type pancreatic cancer circulating tumor cells. Downstream mutational analyses will be performed to confirm identity of the cells.

Both portal venous and peripheral blood will be processed through a cell surface marker-based platform, which contains antibodies for epithelial cell markers on pancreatic cancer circulating tumor cells. Downstream mutational analyses will be performed to confirm identity of the cells.
