ProteomicsAspergillus niger Prolyl endoprotease (An-PEP) for Hydrogen-Deuterium Exchange Mass Spectrometry and Protein Structural Studies
To monitor the structural integrity of therapeutic proteins, hydrogen-deuterium exchange mass spectrometry (HDX-MS) is increasingly utilized in the pharmaceutical industry. The successful outcome of HDX-MS analyses depends on the sample preparation conditions, which involve the rapid digestion of pr...

ProteomicsMirroring the charged termini; ETD/HCD fragmentation characteristics of LysargiNase and tryptic peptides and their benefits for peptide sequencing in proteomics
A key step in proteomics is the digestion of proteins into peptides, so far largely done by using trypsin. Tryptic digestion leads to peptides that in ESI-MS attain predominantly two charges, via protonation at the free N-terminus and at the C-terminal basic residue Arginine or Lysine. These peptide...
