Split-GFP graphene grid captures tagged proteins for 2.58 Å cryo-EM
A bioRxiv preprint presents SGFP–G, a split-GFP graphene grid that selectively captures GFP11-tagged proteins and lets researchers check enrichment by fluorescence before vitrification. The authors demonstrated the platform with apoferritin and obtained a 2.58 Å cryo-EM reconstruction.
