Each biochip contains 4 capillaries in parallel with a membrane of pore size 2-10 um diameter separating them from a microwell underneath.  Chemoattractants can be placed inside the well for subsequent study of cell migration through the membrane under shear flow.  Each pack contains 10 biochips = 40 assays.
