Subcutaneous fat tissue for diagnosis and studies of systemic amyloidosis

The systemic amyloidoses comprise a biochemically heterogeneous group of potentially lethal disorders. An early and precise diagnosis is crucial for the treatment and prognosis. Subcutaneous fat biopsy is a simple and safe method to obtain a diagnosis of systemic amyloidosis and the material can be used for exact determination of amyloid type. A method is described for immunochemical typing of the amyloid based on Western blot analysis combined with specific amyloid fibril protein antibodies. (C) 2006 Elsevier GmbH. All rights reserved.
