This Bachelor Thesis deals with the topic Alzheimer’s disease which belongs to the group of neurodegenerative diseases. Alzheimer’s disease is responsible for about 60 percent of all cases of neurodegenerative diseases. Patients suffer from cognitive decline because of the building of amyloid plaques, which consist of beta amyloid and get deposited in the human brain. One cause for the building of senile plaques is the change of the activity of the β-secretases, which cleaves the transmembrane hydrophobic domain, the amyloid β-peptide, from the Amyloid Precursorprotein. Due to unknown processes, the amyloid beta protein forms fibrils, which get condensed bit by bit. In the context of this Bachelor Thesis, three biomarkers that are independent from each other, get examined through gel electrophoresis, Western Blot, antibody incubation and fluorescence-, or rather chemo luminescence analysis. The aim of this study is to do a progress for the diagnostic relevance of ADAM10, BACE-1 and Tropomyosin in human platelets through their significance. This significance gets calculated by a T-Test. In the following Thesis, back-ground information and statistical results were discussed.
