A biomolecular interaction analyzer is a device that serves as a powerful tool for scientists seeking to further understand interactions between biomolecules such as proteins, DNA, RNA, and small molecules. These instruments enable researchers to measure the strength these interactions.
There is a wide range of automated biomolecular interaction analyzers. These include surface plasmon resonance (SPR) instruments, isothermal titration calorimetry (ITC) machines, and microscale thermophoresis (MST) devices. Despite their differences, these analyzers all rely on their ability to detect changes in the physical or chemical properties of biomolecules.
