Mass spectrometry analyses of GPX isoforms purified over BSP Sepharose. The top panel indicates the profile of A280 absorbance and GPX4 activity when purified over BSP Sepharose, as shown in Fig. 5A and B, with the eluted proteins in collected fractions further analyzed using mass spectrometry as indicated in A and B. In A) the mass-spectrometry spectra and deconvolution of GPX4 species identified in fractions A of the top panel are shown. In B) the corresponding analyses of the B fractions are shown.
