Lupus Erythematosus: Comparison of Functional Activities vs Protein Concentrations of C3 and C4, Antinuclear Antibody Levels, and Skin Immunofluorescence
Abstract:Lupus erythematosus (LE) is an immunemediated disease which may feature profound degenerative and inflammatory reactions. Sera and biopsy specimens from patients with LE were tested in four different assays. Serum C3 and C4 levels were measured by functional hemolytic titrations and by quantification in radial immunodiffusion plates by using antisera to β1C/β1A and C4 (β1E). Antinuclear antibody (ANA) levels were determined by an indirect immunofluorescent method with mouse fibroblast cells and conjugated anti… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
