Fourier transform infrared spectroscopy
Also known as: FTIR
Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Vibrational spectroscopies, such as Fourier transform infrared (FTIR) and Raman, are powerful tools that are sensitive to the secondary structure of proteins and have been widely used to investigate protein misfolding and aggregation.
Usefulness & Problems
Why this is useful
FTIR is a vibrational spectroscopy method used to read out protein secondary-structure features during misfolding and aggregation. In this review it is presented as a core approach for studying oligomers and amyloid fibrils.; probing protein secondary structure; investigating protein misfolding and aggregation; studying structural characteristics of amyloid aggregates

It requires FTIR spectroscopy instrumentation and protein or peptide samples undergoing aggregation. Site-specific extensions may require labeled samples, but that is not necessary for generic FTIR use.; requires vibrational spectroscopy instrumentation
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
