Abstract:
High purity and sequence homogeneity of intrinsically disordered proteins are prerequisites for reproducible studies of the kinetics and equilibrium of their self-assembly reactions. Starting from the pure state enables quantitative studies of intrinsic and extrinsic factors in the process to understand its molecular determinants. Here we outline detailed protocols for recombinant expression and purification of ultra-pure amyloid β peptide (Aβ) in sequence homogeneous form, which allows for the setup of reproducible kinetic self-assembly experiments.
