Correlation of Cutaneous Immunoreactants in Lesional Skin with the Serological Disorders and Disease Activity of Systemic Lupus Erythematosus
Figure 2
Deposit of immunoreactants along epidermal-dermal junction in lesional skin.
Skin sections were incubated with fluorescein isothiocyanate (FITC)-conjugated anti-human IgG, IgA, IgM, and C3 antibodies and visualized with a fluorescence microscope. A and B indicates the staining patterns of single immunoreactant detected from individual biopsy. The representative staining of the coexistence of two and three immunoreactants from two biopsies were shown in C and D, respectively. N.C, negative control without adding FITC-conjugated antibody.
