Fluorescent Substrates
Fluorescent substrates are molecules that emit fluorescence when enzymatically converted to a product. These substrates are valuable in detecting and quantifying enzyme activity with high sensitivity and specificity. Fluorescent substrates are widely used in a variety of applications, including live-cell imaging, flow cytometry, and fluorescence-based assays. They enable researchers to study enzyme kinetics, localization, and interactions in real-time. At CymitQuimica, we offer a comprehensive range of high-quality fluorescent substrates to support your research in biochemistry, molecular biology, and diagnostics.
