From: Serum proteome analysis identifies a potential biomarker for axial psoriatic arthritis
Overview of the experimental workflow. This research is mainly divided into the discovery phase and the verification phase. Liquid chromatography-mass spectrometry (LC-MS/MS) for data-independent acquisition (DIA) was used for biomarker discovery. Random forest, lasso regression, and Boruta algorithm were used to find putative biomarkers that were brought forward for verification with enzyme-linked immunosorbent assay (ELISA). axPsA axial psoriatic arthritis, pPsA peripheral psoriatic arthritis, HC healthy control
