Figure 3From: Automated evaluation of autoantibodies on human epithelial-2 cells as an approach to standardize cell-based immunofluorescence testsImmunofluorescence patterns of two sera (a, b) which were both assessed as positive with speckled pattern by AKLIDES® system but revealed staining of the nuclear membrane by visual examination. Green color: fluorescein isothiocyanate staining of autoantibody; blue color: 4',6-diamidino-2-phenylindol staining of chromatin.Back to article page
