Webb1 mars 2013 · Low pH has been known to cause protein aggregation by altering the physiochemical properties of the product and causing instability of the primary structure (8–11). During crossflow filtration, the protein may be exposed to shear rates from 1000–10,000 s -1 for a few seconds as it passes through the membrane (12). WebbAmyloids are aggregates of proteins characterised by a fibrillar morphology of typically 7–13 nm in diameter, a β-sheet secondary structure (known as cross-β) and ability to be stained by particular dyes, …
