In this review from Bioanalysis, the authors concisely introduce coated blade spray’s operational fundamentals and to consider how it correlates/contrasts with existing direct-to-MS technologies suitable for bioanalytical applications.
An author’s perspective: Germán Augusto Gómez-Ríos on shifting the paradigm of direct sample introduction to MS
We talk to Germán Augusto Gómez-Ríos about shifting the paradigm of direct sample introduction to MS.
Evaluation of Recombinant, Chemically Treated Trypsin in Proteomics and Protein Characterization Assays
We compared recombinant trypsin to native-source in various MS workflows.
Native source trypsin is dimethylated to prevent autolysis and TPCK treated to inhibit chymotrypsin.
Native and recombinant trypsins gave similar amounts of proteins and peptides identified in a complex mixture.
TIC of a single-protein digest revealed more complete peptide processing by recombinant trypsins relative to native trypsin.
Trypsin dimethylation leads to slower processing but with fewer autolytic peptides present.
