Applied Biosystems™ Protein Thermal Shift™ kits allow users to employ a dye that binds to exposed hydrophobic residues to monitor the thermal stability of proteins using a real-time PCR instrument in order to identify buffer conditions that stabilize the protein of interest or screen libraries of ligands for compounds that bind the protein of interest.

Save Time and Money with Your Sample Screening
This solution significantly reduces the time and cost associated with screening samples relative to currently available methods. Protein Thermal Shift™ products that are run on our real-time PCR systems enable researchers to inexpensively and efficiently:

• Screen samples for relative protein thermal stability
• Screen molecules (e.g. small molecule drug candidates, fragment-based libraries, and antibodies) for ligand binding to proteins in a high-throughput manner
• Screen samples for stability changes after protein point mutations or modifications
• Systematically identify suitable⁄optimal buffer conditions for the measurement of protein-ligand interactions, production of stable protein preparations, protein crystallization, and storage of proteins
• Quickly QC protein preps to ensure protein integrity and⁄or purity

Two Kits to Choose From
The Protein Thermal Shift™ Dye Kit contains the dye and buffer for performing protein thermal shift experiments, enough for up to 1000 reactions. The Protein Thermal Shift™ Starter Kit contains the Dye Kit plus a control protein and control ligand for test experiments and troubleshooting. The Protein Thermal Shift™ Starter Kit components are packaged in two boxes, one to be stored at -20°C and the other at 4°C, for maximum flexibility in reagent formulation.

Simplify Analysis with Protein Thermal Shift™ Software
Our complete Protein Thermal Shift™ solution includes analysis software which is compatible with run files generated from five of our real-time PCR systems: StepOne™ Real-Time PCR System, StepOnePlus™ Real-Time PCR system, 7500 Fast Real-Time PCR System, and ViiA™7 Real-Time PCR System.

よくあるご質問(FAQ)

Protein Thermal Meltの反応系に必要なタンパク量はどのくらいですか?

最適濃度は検証実験を経て決定されるのが望ましいですが、1反応あたり0.05–5 µg 、平均して1 µg程度が適度な濃度です。

どの装置がProtein Thermal Shift解析に対応していますか?

QuantStudio, ViiA 7, 7500/7500F (with SDS v2.0.x), or the StepOne/StepOnePlus systems

In the Protein Thermal Shift Assay, my replicates have different levels of fluorescence. Is this a problem?

We recommend looking at the spread in Tm, which is more important than the relative fluorescence.

What can I do for a protein that starts out high and then shows a region of melt (flattening of the curve, but no real rise in signal) when performing a Protein Thermal Shift assay?

Some proteins have hydrophobic residues on the surface and the dye binds to these residues. Heating results in unfolding of the protein causing more hydrophobic residues to be exposed. The dyes bind preferentially to these inner locations and so there is a flattening (or a very low rise) of the melt discernable in the melt profile. If there is no positive slope, you will not get a Boltzmann Tm, but you should still get a derivative one. And you can always draw a manual region to get a Tm out. Some proteins will not work with this technology if the hydrophobic residues are already exposed on the surface and the dye binds strongly to it. Please contact Technical Support at techsupport@thermofisher.com about the possibility of other dyes being available for this issue.

I am getting an error message when I try to open my *.eds data file in the Protein Thermal Shift Software? What should I do?

Make sure that you first open the file in the corresponding instrument software, click “Analyze”, and then save the file, before trying to open with the Protein Thermal Shift Software. The file must first be analyzed before it can be used in the Protein Thermal Shift Software.
