Introduction

Intrinsically disordered proteins (IDPs) are proteins that lack secondary and/or tertiary structure under physiological conditions. These proteins are very abundant in eukaryotic proteomes and play crucial roles in all molecular mechanisms underlying the response to environmental challenges. In plants, different IDPs involved in stress response have been identified and characterized.

Principle

Differential Scanning Fluorimetry measures protein thermal unfolding by monitoring changes in fluorescence emission of a sample upon heating. This allows the determination of protein thermostability and complex formation even with weakly binding ligands by thermal shift assay. Differential Scanning Fluorimetry is therefore ideally suited for screening of optimum buffer conditions like pH, buffer composition and ionic strength. The technique is applicable to any biological sample, from soluble proteins to integral membrane proteins.

Applications

To identify low-molecular-weight ligands that bind and stabilize purified proteins.
To measure the denaturation and unfolding of proteins.
