Comparison of pre- and post-change batches of Enbrel® upon native mass spectrometry at the intact protein level. a Mirror plot of deconvoluted mass spectra of Enbrel® EU pre- and post-change batch 1. b Mirror plot of deconvoluted mass spectra of Enbrel® EU post-change batches 1 and 2. Spectra were acquired at Rset = 35,000 at m/z 200. Mass spectra were acquired with identical instrument settings (SID 100 eV; CE 25 eV)
