It is now 25 years since we commenced the study of the negative-ion fragmentations of peptides and we have recently concluded this research with investigations of the negative-ion chemistry of most post-translational functional groups. Our first nega

Ricin is a toxic protein produced in the seeds of the castor bean plant. The toxicity of the protein and the ease in which it can be extracted from the seeds makes it a potential biological warfare agent. There has been extensive work in the developm

Buffers and detergents are notorious for suppression of analyte signal in electrospray and MALDI mass spectrometry and, invariably, analysts will take steps to remove these contaminants before MS analysis. However, we have found serendipitously that

Eugenin [pGluGlnAspTyr(SO3)ValPheMetHisProPhe-NH2] has been isolated from the pouches of female Tammar wallabies (Macropus eugenii) carrying young in the early lactation period. The sequence of eugenin has been determined using a combination of posit

The electrospray negative ion mass spectra of citropin 1.1 (GLFDVIKKVASVIGGL-NH 2 ) and of synthetically modified analogues show loss of an internal Val residue from both the ( M − H) − anion and certain fragment anions. The negative ion spectra
