title: Cuticular proteins from the shrimp, Pandalus borealis.
abstract: 1. The percentages of mineral salts, chitin, and urea-extractable and non-extractable proteins were determined in pieces of cuticle from selected body regions of the shrimp, Pandalus borealis. 2. Two-dimensional gel-electrophoresis of the urea-extractable proteins shows that a large number of different proteins are present. Identical protein patterns are obtained from the various cuticular regions. 3. A fractionation scheme is presented, which is suitable for obtaining the major proteins in quantities sufficient for further characterization. The amino acid compositions are reported for several of the proteins.
