Fig. 1. Tethering DLPs to functionalized surfaces.
(a) Schematic to illustrate the immunocapture procedure used to tether asynchronously transcribing RV DLPs to antibody (IgG)-decorated surfaces via protein A adaptors. (b) Transcribing DLPs tethered to EM grids or SiN microchips in the presence of VP6-specific IgGs showed varying lengths of associated mRNA transcripts (white arrows) in cryo-EM images. (c) DLPs prepared in the absence of nucleotides needed for transcription do not show associated mRNA in cryo-EM images. (e) EM specimens prepared in the absence of IgGs generally failed to recruit DLPs. Scale bar is 100 nm.
