Images of areas from master gels demonstrate the expression of ‘synovial specific’ proteins (A- spots 23, 25, 29, 36) in synovial fluids and ‘plasma specific’ expression (B- spots 2, 4, 9, 10). Subsequent qualitative subtraction of plasma from matched synovial fluid ‘master’ gels revealed a population of proteins uniquely expressed in the joint in JIA patients.
