Tally of Dopa-containing proteins present in the byssal plaques of Mytilus species (Me= M. edulis; Mc= M. californianus) and their respective adhesion to mica as measured by the surface forces apparatus. For best comparison, testing conditions in all cases were at pH 5.5, ionic strength 0.10 M, 1 atm and 20 °C after a 60 min contact, and were selected to enable comparisons of all mfps.
