Abstract

We report the development of a high‐level bacterial expression system for the Alzheimer’s disease‐associated amyloid β‐peptide (Aβ), together with a scaleable and inexpensive purification procedure. Aβ(1–40) and Aβ(1–42) coding sequences together with added ATG codons were cloned directly into a Pet vector to facilitate production of Met‐Aβ(1–40) and Met‐Aβ(1–42), referred to as Aβ(Μ1–40) and Aβ(Μ1–42), respectively. The expression sequences were designed using codons preferred by Escherichia coli, and the two peptides were expressed in this host in inclusion bodies. Peptides were purified from inclusion bodies using a combination of anion‐exchange chromatography and centrifugal filtration. The method described requires little specialized equipment and provides a facile and inexpensive procedure for production of large amounts of very pure Aβ peptides. Recombinant peptides generated using this protocol produced amyloid fibrils that were indistinguishable from those formed by chemically synthesized Aβ1–40 and Aβ1–42. Formation of fibrils by all peptides was concentration‐dependent, and exhibited kinetics typical of a nucleation‐dependent polymerization reaction. Recombinant and synthetic peptides exhibited a similar toxic effect on hippocampal neurons, with acute treatment causing inhibition of MTT reduction, and chronic treatment resulting in neuritic degeneration and cell loss.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
