Workflow for the proteomics detection in BAL specimen and subsequent validation study. The overall strategy of our study consists of following steps: (1) recovery of peptides from BAL samples, (2) capture of formerly N-linked glycopeptides using SPEG method, (3) Orbitrap Velos LC-MS/MS analysis, (4) identification and quantification of protein/peptide using Proteome Discoverer and SIEVE software, (5) analysis and comparison of the N-glycoprotein abundance in different BAL specimens, and (6) validation studies by using an ELISA assay.
