We have successfully performed series of interactionmeasurements of protein-protein and protein-nucleic acid by using MicroScaleThermophoresis (MST) technology. MST provides a very easy approach to quantifybinding affinity. It only takes a short amount of time to set up experimentsand gets high quality data. We benefited from the low sample consumption,immobilization-free, possibility to choose the buffer freely, especially workingwith sensitive samples. The technical support and customer service fromNanoTemper are excellent. We are willing to develop more applications with MSTsystem in the future, and strongly recommend the system to research groupslooking for an easy and fast quantitative binding assay.

MST是一个具有高度灵活性和功能强大的研究工具。由于它具有较好的鲁棒性,对溶液成分、待测分子和样品数量要求不高,特别适合对难以检测的分子间相互作用进行研究。对于整合在脂质双分子层里的全长膜蛋白与其它物质相互作用进行分析时,几乎是当前最直接、最适用的方法。
本实验室主攻细菌受体组氨酸激酶的分子识别机制,必须利用蛋白脂质体、Nanodisc等膜蛋白技术进行分析。基于MST技术,我们已经做出了多项细菌感知寄主与环境刺激的重要科学发现,成果发表在包括Cell Reports, PLoS Pathogens和MolPlant-Microbe Interact在内的期刊上。周边实验室利用该设备开展了配体-受体互作、蛋白-DNA互作等实验也获得了理想的结果,成果发表在Nature, Nat Genet等高影响力期刊上。因此,MST是开展分子间相互作用研究的强大工具之一。
"We strongly recommend MST technology for its low material consumption, short measurement time and very wide application range."
"Part of our research focus on the protein structural-function basis for iron metabolism of pathogenic microorganisms. We measured the dissociated constant for periplasmic binding protein and siderophore through MST technology. Because siderophore is extremely insoluble, it's difficult for us to complete that task via other methods such as ITC and SPR. We strongly recommend MST technology for its low material consumption, short measurement time and very wide application range."
"Via MST, we measured interactions, that have been difficult to detect and quantify with other interaction technologies"
"Our recent research is focused on the critical pathogenic protein & complex from pathogenic microbes and the Protein structure-functional basis for some endogenous disease. Via MST, we measured the Protein-DNA interaction, that have been difficult to detect and quantify with other standard biomolecule interaction technologies (like SPR and ITC) because of the conformation/immobilization-sensitive and very little heat changes of our samples. MST technology can be used as a complementary technology to the traditional methods in these fields. We can strongly recommend MST technology for its low material consumption, short measurement times and broad application range for molecule-interaction studies."

"Our recent research is focused on the molecular basis of herbicide resistance and exploiting new target sites of herbicide, such as PPI of AHAS. Via MST, we measured the Protein-Protein interaction, that have been difficult to detect and quantify with ITC because of instability of the protein and very little heat changes of our samples. The MST technology can be used as a complementary technology to the traditional methods in these fields. We can strongly recommend the MST technology for its low material consumption, short measurement times and broad application range in the field of molecule interaction studies."
"MST technology turns out to be an excellent way to determine such weak interactions between small fragments and protein"
"We are interested in applying computational fragment-based strategy to identify lead compounds to block protein-protein interactions in RAS pathway. Generally, the identified fragments are weak binders with binding affinities ranging from millimolar to micromolar. For such weak interactions, it is difficult to set up reliable biochemical assays or binding assays using ITC or SPR techniques. Fortunately, MST technology turns out to be an excellent way to determine such weak interactions between small fragments and protein in our system of interest. We efficiently and reliably performed our experimental binding measurement using minimum amount of protein and fragments.
We are also interested in studying the regulation mechanism of a nuclear hormone receptor, which plays fundamental role in homeostasis and metabolism. The nuclear hormone receptor can be modified by an important enzyme to regulate the expression of specific genes and cause certain metabolic disease. We wanted to measure the binding affinity between these two proteins. Interestingly, this interaction is extremely difficult for the standard binding affinity measurement approach, with no exothermal or endothermal signals using ITC. While using MST technology, we have successfully detected this interaction. We strongly recommend MST technology for its low material consumption, short measurement time, and very high sensitivity."
"It is distinguished in low sample consumption, fast measurement and immobilization-free setup."
We used Microscale Thermophoresis (MST) to measure the interaction between large molecular chaperones with molecular weight up to 800 kDa. It is distinguished in low sample consumption, fast measurement and immobilization-free setup. We found that the biophysical data obtained from MST are in good agreement with those obtained from SPR or ITC. MST technology will facilitate our research on various interactions.
"We strongly recommend MST technology for its low material consumption, short measurement times and very high sensitivity"
Our lab focuses on the importance for telomere and telomerase to maintain the integrity of genomes and the stability of chromosomes. Large amount of proteins and protein complexes are involved in epigenetics, which play essential rotes in controlling many cellular events. We are employing MicroScale Thermophoresis (MST) in determining the interactions of proteins/protein complexes to ssDNA/RNA. It's easier to measure the protein-protein or protein-nucleic acid interaction, especially for those sensitive samples, that has been difficult to detect and quantify with ITC or SPR. We benefited from the low sarnple consumption, the fast measurements, the broad application range and the possibility to choose the buffer freely, resulting in highly reproducible data. We strongly recommend MST technology for its low material consumption, short measurement times and very high sensitivity.
