The FLOW CHAMBER SURFACE dimensions were fixed at 100 × 60 SURFACE UNITS. Each SURFACE grid space maps to approximately 1 μm2 of effective flow chamber surface area. a Values listed in units of [μg/mL] are the concentrations of the solutions of receptors used to coat the parallel plate flow chamber surfaces and are not meant to represent the concentrations of receptors found on the parallel plate surface.
