title: Plasma desorption mass spectrometry coupled with conventional peptide sequencing techniques.
abstract: The mass of intact and enzymatically derived fragments of cecropin B, an antibacterial protein from the Chinese oak silk moth, Antherea pernyi, have been determined by 252Cf plasma desorption time-of-flight mass spectrometry. As a result, the carboxy terminal amino acid sequence of the protein was established.
