ERGFP_NS accumulates in the ER in SAYSD1 and TRAPPC8 knockdown cells. (A) HEK293T cells transfected with ERGFP_NS and SAYSD1 siRNA were stained with calreticulin antibodies (red) and Hoechst (blue). Scale bar, 5 μm. (B) HEK293T cells transfected with ERGFP_NS and SAYSD1 siRNA were stained with calreticulin antibodies. Arrowheads indicate a few examples of ERGFP_NS and calreticulin co-localization. Scale bar, 5 μm.
