Intended use

C1,2C as a biomarker is used in the investigation of the progression of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, reflecting cartilage, ligament, skin, synovium/capsule, lung and bone damage or inflammation or repair, in human as well as some animal models. Increased serum C1,2C concentrations give an indication of a rapid progressive joint damage in RA.
