From: Characterization of the pigmented shell-forming proteome of the common grove snail Cepaea nemoralis
A comparison of the protein-associated pigments and PAGE profiles of proteins isolated from the shells of H. asinina and C. nemoralis . A. A representative SDS-PAGE gel of proteins isolated from shells of juvenile H. asinina. This gel is unstained (the protein marker is pre-stained) allowing the red and blue pigment-associated proteins to be visualized (arrows). B. A representative LDS-PAGE analysis of C. nemoralis acid-soluble and –insoluble proteins extracted from shell fragments either treated with or without a sodium hypochlorite-plus-sonication pre-treatment. Protein extractions which displayed such electrophoretic patterns were subjected to FASP (Filter-Aided Sample Preparation) sample preparation and proteomic analysis.
