TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) assay kits are used to analyze the binding of two interacting partner molecules, such as proteins. 

These kits are commonly used in cell signaling research and are designed to provide accurate and reliable detection of target biomarkers or molecules in biological sample

These TR-FRET assay kits are designed to be easy to use and provide researchers with the necessary tools for studying protein interactions and cell signaling pathways.
