Differential Scanning Fluorimetry provides high throughput data on silk protein transitions.

Differential Scanning Fluorimetry provides high throughput data on silk protein transitions.

Here we present a set of measurements using Differential Scanning Fluorimetry (DSF) as an inexpensive, high throughput screening method to investigate the folding of silk protein molecules as they abandon their first native melt conformation, dehydrate and denature into their final solid filament conformation. Our first data and analyses comparing silks from spiders, mulberry and wild silkworms...

Differential scanning fluorimetry illuminates silk feedstock stability and processability.

The ability to design and implement silk feedstock formulations for tailored spinning has so far eluded the bioengineers. Recently, the high throughput screening technique of differential scanning fluorimetry (DSF) demonstrated the link between the instability transition temperature (Ti) and the processability of the silk feedstock. Using DSF we screened a large set of chemicals known to affect...

Use of differential scanning fluorimetry as a high-throughput assay to identify nuclear receptor ligands

Identification of ligands that interact with nuclear receptors is both a major biological problem and an important initial step in drug discovery. Several in vitro and in vivo techniques are commonly used to screen ligand candidates against nuclear receptors; however, none of the current assays allow screening without modification of either the protein and/or the ligand in a high-throughput fas...

Determination of Protein-ligand Interactions Using Differential Scanning Fluorimetry

A wide range of methods are currently available for determining the dissociation constant between a protein and interacting small molecules. However, most of these require access to specialist equipment, and often require a degree of expertise to effectively establish reliable experiments and analyze data. Differential scanning fluorimetry (DSF) is being increasingly used as a robust method for...
