Proteomics quantification of striatal fraction from DAT-KO and WT rats

The study aimed to find out quantitative changes at the protein level in the total membrane fraction enriched in synaptosomes and mitochondria upon the absence of the dopamine transporter in rat brain. Therefore, the brain of male rats (Wister Han) DAT-wildtype and DAT-knockout animals, were dissected and the striatum was used for the enrichment of the synaptic and mitochondrial membrane fraction. The proteins of the total membrane fraction were further tryptically digested and analysed via label-free LC-MSMS.
