May Update

Currently, my task is to perform fragmentation on tetrapeptides of lysine and lysine homologs. Right now, I am currently investigating the b2+ ion structure and exchange of XAAA tetrapeptides (X being lysine or lysine homologs and A being alanine). I am currently restocking and diluting necessary solutions and cleaning out inventory. In addition, I am…

Abstract: Hydrogen-Deuterium Exchange and Fragmentation Studies of Peptides and Amino Acids

Mass spectrometry-based proteomics experiments, are broadly related to automated peptide sequencing. Mass spectrometry experimentation provides structure elucidation and give a relative understanding of gas-phase properties, fragmentation, and interactions between amino acid side groups, which are often neglected in automated peptide sequencing algorithms. This summer, I will performing H/D exchange on various amino acids and peptide…
