Findings of dual immunofluorescence staining for IgG and nephrin using confocal microscopy and super-resolution microscopy (SRM) in graft biopsies of the first biopsy of a transplanted kidney at our hospital. Green represents IgG, and red represents nephrin. Owing to resolution limitations, the co-localization of nephrin and IgG in the glomerular capillary wall could not be determined in confocal microscopy. However, their co-localization was confirmed with SRM
