Enhancing the Efficiency of Conventional Surface Immunoassays Within Standard Labware Using Microscale Flows.

In this chapter, we present the design and fabrication of a device and implementation of a protocol to realize increased efficiency of immunoassays within microtiter plates. The device, WellProbe, is a 3D-structured probe that can be used to deliver precise flows at the bottom of standard well plates to establish concentric areas of shear stress intensities using hydrodynamically confined flows. The protocols involve both operation and data analysis.
