"Extraction and Anaysis of Neuropeptides in Lobsters" by MALDI- FTMS."
Matrix assisted laser/desorption ionization (MALDI) Fourier transform mass spectrometry (FTMS) has been used to study the neuropeptide distributions in nerve cells from the stomatogastric nervous system (STNS) of the Maine lobster, Homarus americanus. Previous studies were conducted using direct tissue analysis involving peptide extraction on the face of the ionization surface. In this study, a microextraction and delipidation procedure was designed to improve signal intensity and remove contaminants (phospholipids and salts). Two different microextraction and delipidation procedures were attempted during the course of the project. The second procedure, which used a tissue extraction solvent of methanol, nanopure water and acetic acid and a delipidation solvent of chloroform, resulted in efficient extraction of neuropeptides from both the sinus gland of H. americanus and the pericardial organ of Pugettia producta. Analysis of one-twentieth of the total extract resulted in spectra with signal-to-noise ratios comparable to or better than direct tissue spectra. Permethylation reactions conducted on dried extracts showed a reduction in Asp-Xxx cleavages, which were abundant in direct tissue and extract spectra. The permethylated extracts showed a complete permethylation of all known neuropeptides in the H. americanus sinus gland.
