SwiftFluo® TR-FRET Kinase Assay Kits: Making High-throughput Inhibitor Screening Smarter
By Sino Biological
Kinases play a critical role in cellular signaling and serve as key targets for small-molecule drug discovery. As of November 2025, 100 small-molecule protein kinase inhibitors have been approved by the FDA, with numerous candidates in clinical trials. Traditional screening methods such as radioactive assays, ELISA, and fluorescence intensity-based approaches, are limited by low throughput and complex procedures. TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) technology, with its high sensitivity, low background, and ease of automation, provides an efficient solution for kinase activity detection and high-throughput inhibitor screening.
Sino Biological has newly launched a series of ready-to-use TR-FRET kinase assay kits with extensive coverage across diverse kinase families. Featuring simplicity, speed, high specificity, high sensitivity, and strong reproducibility, these kits support researchers to perform rapid and reliable high-throughput kinase drug screening.
