Fig 7. The LET-653 ZPc domain binds aggregates in vitro.
A-G) Single confocal slices of freshly thawed cell media. A-B) Aggregates were non-fluorescent in EV- or SfGFP- transfected cell media. C) Aggregates were fluorescent in SfGFP::LET-653(ZP)-transfected media. D) SfGFP::LET-653(ZPn)-transfected media resembled negative controls; E) SfGFP::LET-653(ZPc) transfected cell media contained aggregates of high fluorescence intensity. F-G) Aggregates in media containing LET-653(ZP)::SfGFP and LET-653(ZP, AYAA)::SfGFP were similarly fluorescent. H) Quantification of aggregate fluorescence intensity. ***p<0.0001; two-tailed Mann-Whitney U test. Error bars; standard error. All experiments were performed on media from transfection 2.
