GRP78 expression on human glioma cell lines. Surface immunofluorescence staining of two human glioma cell lines (U-251MG and U-87MG) showing the localization of GRP78 at the cell surface. Cells were stained with GRP78 polyclonal antibodies and Cy3-conjuncted secondary antibodies. Control cells were stained with only Cy3-conjuncted secondary antibodies. Scale bar = 10 μm
