Western blot quantification of aggrecan fragments in human synovial fluid indicates differences in fragment patterns between joint diseases.
OBJECTIVE: To develop a Western blot method for quantification of multiple aggrecan fragments in human synovial fluids (SFs). METHOD: SF aggrecan fragments were prepared from knee healthy (reference), knee injury and arthritis subjects by CsCl gradient centrifugations collecting D1 fractions. Samples were analyzed by Western blot, using antibodies against the N-terminal epitope ARGS and the G3 dom
