Fischartbestimmung von Caviar durch Protein- und DNA-Analyse

Deutscher Caviar, made from roe of lumpfish or capelin, gives species specific patterns in protein electrophoresis.The same techniques can be used to differentiate caviar from salmon and trout. The differentiation of sturgeon caviar (beluga, osietra, sevruga) is possible by isoelectric focusing, but...

Description
Summary:Deutscher Caviar, made from roe of lumpfish or capelin, gives species specific patterns in protein electrophoresis.The same techniques can be used to differentiate caviar from salmon and trout. The differentiation of sturgeon caviar (beluga, osietra, sevruga) is possible by isoelectric focusing, but not by SDS-PAGE. PCR-based methods of DNA-analysis for identification of the origin of sturgeon caviar are under development. Johann Heinrich von Thünen-Institute, Federal Research Institute for Rural Areas, Forestry and Fisheries began publishing the Informationen aus der Fischereiforschung = Information on Fishery research in 2010.
