A beta fibrillogenesis: kinetic parameters for fibril formation from congo red binding.
Using Scatchard analysis, we have formulated as a function of time and pH the relationship between the binding of Congo red to Alzheimer's beta-amyloid and the aggregation number (i.e., monomer concentration within fibrils) as defined by nucleation-dependent self-assembly. This provides a basis on which to determine the kinetic parameters for fibril formation from the observed concentration of bound Congo red.
