1. An assay cassette comprising:

  • a capture surface that carries an array of spaced-apart regions of ligand receptors, and a liquid passage system constructed to direct over the array a slow flow of assay-supporting liquids having Reynolds numbers less than about 1, the liquids including a ligand-containing liquid, the liquid passage system including a gas bubble removal system to which the liquids are exposed, the gas bubble removal system constructed and arranged to remove gas micro-bubbles from the liquids prior to exposure of the liquids to the array.
