To maintain acinar units in place throughout the FlexStation 3 measurements, Corning® Cell-Tak adhesive was used to coat the half-area, 96-well assay plates which were used in these experiments. Corning® Cell-Tak adhesive is a formulation of the “polyphenolic proteins” [19] extracted from the marine mussel, Mytilus edulis. This family of related proteins is the key component of the glue secreted by the mussel to anchor itself to solid structures in its natural environment [20].
