(a) Raw ESI–MS data (TIC = 3.12 × 104) and deconvoluted mass spectrum of lysozyme contaminated with OPPF2067 prior to crystallization. (b) Raw ESI–MS data (TIC = 7.56 × 103) and deconvoluted mass spectrum of crystal-derived lysozyme sample with contaminating protein removed. Crystal grown in 20% PEG 8000, 0.2 M MgCl2, 0.1 M Tris pH 7.5 and prepared by reservoir-solution and 2 × acetonitrile washing. |
