Techniques to study amyloid fibril formation in vitro
Nilsson MR.. Methods (San Diego, Calif.), 2004-09-01
Topic: Disease mechanisms in lab and animal studies
Amyloid fibrils are ordered aggregates of peptides or proteins that are fibrillar in structure and contribute to the complications of many diseases (e.g., type 2 diabetes mellitus, Alzheimer's disease, and primary systemic amyloidosis). These fibrils can also be prepared in vitro and there are three criteria that define a protein aggregate as an amyloid fibril: green birefringence upon staining with Congo Red, fibrillar morphology, and beta-sheet secondary structure. The purpose of this review is to describe the techniques used to study amyloid fibril formation in vitro, address common errors in the collection and interpretation of data, and open a discussion for a critical review of the criteria currently used to classify a protein aggregate as an amyloid fibril.
Key findings
- Amyloid fibrils are ordered aggregates of peptides or proteins that are fibrillar in structure and contribute to the complications of many diseases (e.g., type 2 diabetes mellitus, Alzheimer's disease, and primary systemic amyloidosis).
- These fibrils can also be prepared in vitro and there are three criteria that define a protein aggregate as an amyloid fibril: green birefringence upon staining with Congo Red, fibrillar morphology, and beta-sheet secondary structure.
- The purpose of this review is to describe the techniques used to study amyloid fibril formation in vitro, address common errors in the collection and interpretation of data, and open a discussion for a critical review of the criteria currently used to classify a protein aggregate as an amyloid fibril.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
