Fig. 3: S100A16 physically interacts with GRP78 in HK-2 cells.

A An interaction between GRP78 and S100A16 was detected by co-immunoprecipitation analysis in normal HK-2 cells. B The colocalization of S100A16 and GRP78 was detected in HK-2 cells by immunofluorescence staining. S100A16 in green, GRP78 in red, and DAPI in blue. Scale bar = 20 μm.
