Multiple batches of S9.6 antibody bind to transfected RNA–DNA hybrids and dsRNA in human cells. Representative confocal images of HeLa cells transfected with ATTO-594 (red)-labeled ssDNA, ssRNA, dsRNA, or RNA–DNA hybrids, followed by immunostaining with S9.6 antibody sourced from Kerafast (green). Inset images are magnified to show overlap of S9.6 signal and ATTO-594 foci. Scale bar is 10 microns; 5 microns for inset images.
