title: Preparative isolation of human beta 2-microglobulin from urine.
abstract: Human beta 2-microglobulin was isolated from the urine of patients with tubular proteinuria by sequential ion exchange and gel filtration chromatography on Sepharose Q fast flow and Sephacryl S-200 respectively. Large volumes of starting material could be processed and yielded a homogeneous preparation of purity 99% or greater with a recovery of about 50% of the immunochemically demonstrable beta 2-microglobulin. This method provides protein suitable for structural studies and investigation of beta 2-microglobulin amyloidogenesis.
