title: Molluscan shell matrix characterization by preparative SDS-PAGE.
abstract: The glycoproteinaceous constituents of molluscan shell matrices usually resist chromatographical fractionation. We describe a protocol that overcomes this difficulty and permits collection of a large amount of shell proteins for further in vitro characterization. After dissolution of the mineral phase, the glycoproteins are fractionated "blind" on a preparative electrophoresis. They are subsequently detected with a polyclonal antibody raised against the whole matrix.
