Since a long time, TdB Labs AB has been manufacturing dextrans labeled with single fluorophores [FITC, TRITC, and Antonia Red (AR)] that are being sold globally. We have now used the same standard and expertise to manufacture dextrans labeled with dual fluorophores that can be effectively used with intravital microscopy and fluorescence imaging. FITC is a dye that is responsive to pH, while TRITC and AR show pH independent behavior. Both the pH probes; FTD of 500kDa and FARD of 20kDa work well in the pH range of 3.5-8.0.
Our offer includes:
Functionality – Dual fluorescence of pH probes makes them highly efficient in accurate detection and monitoring of pH in living cells and tissues.
High Quality – Antonia Red is a proprietary dye that has been developed at TdB Labs AB with well-optimized protocols. All the three fluorophores; FITC, TRITC, and Antonia Red have very high quality that we use in the synthesis of our own fluorescent-labeled dextran products.
Ease of use – Both the pH probes are soluble in water and DMSO. They are also considerably stable both in solution and the solid state.
