S.W. Gotte T.L. Leto P.J. Weldon W.E. Seifert Jr. 1994 <p>Lipids and proteins in the Rathke's gland secretions of the North American mud turtle (<i>Kinosternon subrubrum</i>, Kinosternidae) were analyzed by gas chromatography-mass spectrometry (GC-MS) and SDS-polyacrylamide gel electrophoresis (SDS-PAGE), respectively. Analysis by GC-MS indicates 2,3-dihydroxypropanal and C₃–C₂₄ free or esterified fatty acids. Analysis by SDS-PAGE indicates a major protein component with an approximate molecular mass of 60 kDa and minor components ranging from <i>ca.</i> 23 to 34 kDa. The major component of <i>K. subrubrum</i> glandular secretions exhibits a mobility that matches that of the Kemp's ridley sea turtle (<i>Lepidochelys kempi</i>, Cheloniidae), suggesting that these proteins are evolutionarily conserved.</p> application/pdf 10.1016/0305-0491(94)90029-9 en Elsevier Lipids and proteins in the Rathke's gland secretions of the North American mud turtle (<i>Kinosternon subrubrum</i>) article
