Atypical signaling and functional desensitization response of MAS receptor to peptide ligands. [PDF]
PLoS ONE, 2014 MAS is a G protein-coupled receptor (GPCR) implicated in multiple physiological processes. Several physiological peptide ligands such as angiotensin-(1-7), angiotensin fragments and neuropeptide FF (NPFF) are reported to act on MAS.

Collisional energy dependence of peptide ion fragmentation [PDF]
Journal of the American Society for Mass Spectrometry, 2009 The energy dependence of fragmentation in a collision cell was measured for 2400 protonated peptide ions derived from the digestion of 24 proteins. The collision voltage at which the sum of the fragment ion abundances was equal to the remaining parent ion (V(1/2)) was the principal measure of fragmentation effectiveness.

Proceedings of the National Academy of Sciences of the United States of America, 1993 A rapid method for the identification of known proteins separated by two-dimensional gel electrophoresis is described in which molecular masses of peptide fragments are used to search a protein sequence database.

Brazilian Journal of Medical and Biological Research, 1999 Studies concerning the antigenicity of thyroglobulin fragments allow the characterization of the epitopes but do not consider the role of heavier antigenic fragments that could result in vivo from the action of endoproteases.

A novel framework to quantify uncertainty in peptide-tandem mass spectrum matches with application to nanobody peptide identification [PDF]
arXiv, 2021 Nanobodies are small antibody fragments derived from camelids that selectively bind to antigens. These proteins have marked physicochemical properties that support advanced therapeutics, including treatments for SARS-CoV-2. To realize their potential, bottom-up proteomics via liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been proposed ...

Improved Detection and Fragmentation of Disulphide-Linked Peptides [PDF]
Methods and Protocols, 2018 Characterisation of peptides containing intact disulphide bonds (DSBs) via mass spectrometry is challenging. Our study demonstrates that the addition of aniline to alpha-cyano-4-hydroxycinnamic acid improves detection and fragmentation of complex DSB peptides by matrix-assisted laser desorption/ionization, tandem time-of-flight mass spectrometry (MALDI-

Chronological Profiling of Plasma Native Peptides after Hepatectomy in Pigs: Toward the Discovery of Human Biomarkers for Liver Regeneration. [PDF]
PLoS ONE, 2017 Liver regeneration after partial hepatectomy (PHx) is a time-dependent process, which is tightly regulated by multiple signaling cascades. Failure of this complex process leads to posthepatectomy liver failure (PHLF), which is associated with a high rate
