Since proteins typically aggregate upon denaturation (or form fibrils) the detected species size will go up. This is label-free and independent of specific residues in the protein or buffer composition. The only requirement is that the protein actually aggregates/fibrillates after denaturation and that the protein of interest has been purified.
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Submission of preprints is accepted by all open access journals. Over the last decade, they have been joined by most subscription journals, however publisher policies are often vague or ill-defined. [1] In general, most publishers that permit preprints require that:
In the less extensive technique of equilibrium unfolding, the fractions of folded and unfolded molecules (denoted as and , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the unfolded state, e.g., by adding a denaturant such as guanidinium hydrochloride or urea.
Denaturation midpoint of a protein is defined as the temperature (T m) or concentration of denaturant (C m) at which both the folded and unfolded states are equally populated at equilibrium (assuming two-state protein folding). T m is often determined using a thermal shift assay.
Proteins: Structure, Function, and Bioinformatics is a monthly peer-reviewed scientific journal published by John Wiley & Sons, which was established in 1986 by Cyrus Levinthal. The journal covers research on all aspects protein biochemistry , including computation, function, structure, design, and genetics.
Protein Engineering Design & Selection is a publication of Oxford University Press. Created in 1986, the Journal covers topics related the engineering , design and selection of proteins for use in biotechnology and therapy, and for understanding the fundamental link between protein sequence, structure, dynamics, function, and evolution.
The ICMJE recommendations (full title, "Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals") are a set of guidelines produced by the International Committee of Medical Journal Editors for standardising the ethics, preparation and formatting of manuscripts submitted to biomedical journals for publication.
