Compound screening
Main content
As part of and , we offer high throughput and fragment screening.
High throughput screening (HTS)
The HTS assay we use is a thermal shift assay called differential scanning fluorimetry (DSF) or Thermofluor. The protein of interest is heated up in the presence of a fluorescent probe (Sypro Orange or similar) which reports exposed hydrophobic areas. Thus, you get increased fluorescence when the protein unfolds, which can be used to determine the melting point. If a compound binds to the native state of a protein, there will be a shift in the melting point.
The samples are prepared in 384-well RT-PCR plates, and standard RT-PCR instrument from Roche is used to record the unfolding curves of 384 samples simultaneously.
We have successfully used the screening for several projects:

Fragment screening
For fragment screening, we have a divers 700 compound library, and a library containing 300 small acids. The libraries can either be screened using an Octet red 96 or a Biacore T 200 instrument.

In addition to our own libraries, we also host the 100k and the 1000-member .
