ABSTRACT:
The present invention relates to the use of antibodies against glucose-6-phosphate isomerase (GPI) and like protein for diagnosis of arthritis and the use of said protein for treatment of arthritis. It is also aimed at a process for isolating monoclonal antibodies capable of transferring arthritis and antibodies thereof, as well as a method for determining the anti-arthritis potential of a composition.
