Preformed Fibrils (PFFs) — frequently asked
What are preformed fibrils?
They are amyloid fibrils assembled in vitro from purified monomeric protein under controlled conditions and supplied as a characterised fibrillar stock, so that researchers can seed aggregation directly rather than waiting through a spontaneous nucleation phase.
Why are PFFs used in research?
Fibrils are reported to be seed-competent, templating assembly of the matching soluble protein in cells and tissue. This underpins widely used models of protein propagation and allows aggregation kinetics to be measured with far shorter and more reproducible lag phases.
Which proteins are available as fibrils?
Alpha-synuclein, tau and beta-amyloid fibrils are the most common, generally as human sequences and including mutant and labeled variants. Mixed or complexed preparations are also listed for cross-seeding studies between different amyloid-forming proteins.
