Identification of ligands for bacterial sensor proteins by Differential Scanning Fluorimetry(DSF) (CAT#: STEM-MB-0798-WXH)

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.

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