Protein engineering for better PET radioligands

An approved method for visualization of Amyloid β (Aβ) plaques in patients suffering from Alzheimer's disease is Positron Emission Tomography (PET). This method requires a radiolabeled amyloid ligand. A frequently used molecule is Pittsburgh Compound B (PIB) which is a derivative of Thioflavin T. Radiolabeled PIB is well-suited to visualize insoluble Aβ plaques and has been used for differential diagnosis of AD. However, the PIB signal, giving an estimate of...
