"Our group focuses on the in vitro study of risk factors in Alzheimer’s disease and, as we experienced that the in-house expression and production of the amyloid beta peptide is notoriously difficult, we are continuously dependent on a high quality supply of a large variety of these peptides from commercial source.We started our collaboration with JPT with their request to test a range of their peptides for the ability to produce toxic oligomers and fibrillar networks and were impressed by the rapid supply of a very wide range of high purity peptides with excellent fibril forming properties and toxicity profiles. JPT has shown real valuable know-how and experience in the field of peptide synthesis by their ability to generate high quality preparations of amyloid beta peptide variants which are known for their difficulty to handle."
