Resumen
The invention relates to a method for selecting peptides from proteins of tissues or organs of European hake in order to produce specific antibodies for identifying the origin of individual European hakes, assigning them to the Mediterranean basin or the Atlantic basin. Starting from the brain, peptides located in the following proteins are selected: ATP synthetase, subunit alpha; 14-3-3; and those of the voltage-dependent anion channel, respectively. The invention also relates to the combination of antibodies given the selected peptides, with which an immunodetection method has been designed in order to identify the populations of origin of the European hake. As well as the antibodies produced, the invention also relates to a kit for identifying the origin of the hakes.
