Abstract
An antigen that can be derived from rabbit kidney can be identified by use of suitable rabbit antisera as being non-tissue specific in addition to being an autoantigen, since it had been found to be distributed in kidney, heart, adrenal and liver. The purification of this autoantigen has been accomplished by successive use of four different methods. These were the salting out with ammonium sulphate, gel filtration on Sephadex G-200, dialysis against distilled water, and chromatography on DEAE-cellulose. The heterogeneity of the products derived from the procedure at each step was analysed by means of analytical electrophoresis and ultracentrifugation, and also by gel diffusion precipitation.
