Additional Information
We designed the BromoMELTTM Assay Kit for profiling of compound binding to a collection of human bromodomain proteins. BromoMELTTM is a thermal stability assay (TSA), where heat-induced protein denaturation exposes hydrophobic surfaces that interact with a dye, thereby increasing its fluorescence. A plot of fluorescence versus the gradually increasing temperature is analyzed to obtain a melting temperature (Tm), represented by an inflection point of the curve. Interaction between the protein and a ligand increases protein stability, leading to an increase in Tm.
Workflow:
- Prerun (optional)
- Prepare PCR master mix, including SYPRO Orange dye.
- Pipette reaction plate, including DMSO control, control compound mix, test compound mix in duplicates.
- Run qPCR.
- Perform data analysis using your instrument’s software.
