File Name : figure s1.tif Caption : fig. s1 plasma induces sg formation in flpin sh-sy5y-mscarleti-g3bp1-myc cells stably expressing g3bp1 that were exposed to different concentrations of (a) arsenite and (b) sorbitol for 2h. g3bp1 localization within sgs was confirmed by co- staining the cells for pabp, another stress granule protein. images were taken under 63x magnification, scale bars 10 μm, arrows denote sgs. File Name : figure s2.tif Caption : fig. s2 plasma treatment parameters affecting sg formation were monitored in flpin sh-sy5y-mscarleti-g3bp1-myc cells stably expressing g3bp1 by exposing them to plasma for different time intervals (20 s, 40 s, 60 s, 80 s) and flow rates (slm). cells were monitored for sg formation upon (a) 24 h, (b) 4 h and (c) 2 h incubation. images were taken under 63x magnification, scale bars 10 μm, arrows denote sgs. File Name : figure s3.tif Caption : fig. s3 plasma induces most dynamic sg formation in flpin sh-sy5y-mscarleti-g3bp1-myc cells upon 20 s exposure with 2 and 3 slm and 2h incubation period. images were taken under 63x magnification, scale bars 10 μm, arrows denote sgs.
