Disulfide bonds are valuable constraints in protein structure modeling. The Cys–Cys disulfide bond undergoes specific fragmentation under CID and, therefore, can be considered as a CID-cleavable crosslink. We have recently reported on the benefits of using non-specific digestion with proteinase K for inter-peptide crosslink determination. Here, we describe an updated application of our CID-cleavable...
Spurred on by the growing demand for panels of validated disease biomarkers, increasing efforts have focused on advancing qualitative and quantitative tools for more highly multiplexed and sensitive analyses of a multitude of analytes in various human biofluids. In quantitative proteomics, evolving strategies involve the use of the targeted multiple reaction monitoring (MRM) mode of mass spectrometry...
An immuno-Matrix Assisted Laser Desorption/Ionization (iMALDI) method has been developed using anti-IgG beads to capture anti-AngI and anti-AngII antibodies, which are incubated with a ∼50μL plasma sample to which known amounts of stable-isotope-labeled AngI and AngII have been added. After a short incubation time, the beads are washed, placed directly on a MALDI target, and analyzed by mass spectrometry...
