title: One-step purification by high-performance liquid chromatography of retinal S-antigen.
abstract: A number of subsequent chromatographic techniques are commonly used, over a period of a few days, in order to obtain pure retinal S-antigen (S-Ag), a 50,000-dalton molecular weight protein with strong uveitopathogenic properties. A rapid high-performance liquid chromatographic technique employing a TSK-G3000 SWG gel-filtration column is described for the purification of bovine S-Ag. This single chromatographic step produced S-Ag preparations of high purity and recovery when compared to the conventionally isolated S-Ag.
