- Die SDD-AGE (von engl. semi-denaturing detergent agarose gel electrophoresis ‚halbdenaturierende detergenzvermittelte Agarose-Gelelektrophorese‘) ist ein biochemisches Verfahren, bei dem SDS-resistente Proteinkomplexe, wie z. B. bei Amyloidosen oder Prionenerkrankungen, durch Gelelektrophorese in einem Agarosegel aufgetrennt und nachgewiesen werden. (de)
- In biochemistry and molecular biology, SDD-AGE is short for Semi-Denaturating Detergent Agarose Gel Electrophoresis. This is a method for detecting and characterizing large protein polymers which are stable in 2% SDS at room temperature, unlike most large protein complexes. This method is very useful for studying prions and amyloids, which are characterized by the formation of proteinaceous polymers. Agarose is used for the gel since the SDS-resistant polymers are large (in the 200-4000+ kDa range) and cannot enter a conventional polyacrylamide gel, which has small pores. Agarose on the other hand has large pores, which allows for the separation of polymers. Use of this method allowed researchers to understand that at least some types of prion aggregates existed in a two-level structure - protein molecules grouped into polymers, which are very stable and withstand treatment with 2% SDS at room temperature, and aggregates, which are bundles of polymers, that dissociate under these conditions. Differences in the size of polymers can indicate the efficiency of polymer fragmentation in vivo. (en)
