LINE & Dot

Connective tissue diseases (CTDs) are systemic autoimmune disorders such as systemic lupus erythematosus, systemic sclerosis, and Sjögren’s syndrome. The immune system produces autoantibodies against nuclear and cytoplasmic antigens. These markers support diagnosis, differentiation, and disease monitoring.

Our LINE and Dot assays for connective tissue diseases enable the simultaneous qualitative detection of relevant autoantibodies in a single test format. These include antibodies against dsDNA, Sm, RNP, SSA, SSB, Scl-70, CENP, and Jo-1. The tests deliver clear, reproducible results and support reliable routine diagnostics. They integrate easily into existing laboratory workflows.
