Fig. 6. Purification and cryo-electron microscopy processing of the HCMV gH/UL116/UL141 3-mer.
a, Schematic representation of the expression and purification process for the HCMV gH/UL116/UL141 complex. b, Size exclusion chromatography profile of the gH/UL116/UL141 complex. Fractions were analyzed by SDS-PAGE under non-reducing conditions, with the fraction indicated by blue asterisks used for cryo-EM studies. c, Western blot analysis of fraction 8, probed with anti-His, anti-gH, and anti-strep antibodies to detect UL141, gH, and UL116, respectively. d, Overview of the representative cryo-EM data processing workflow for the gH/UL116/UL141 complex.
