Polarization Standards

Fluorescence polarization (FP) standards are used to calibrate or test fluorescence instrumentation for polarization measurements [25].

Below is a list of polarization standards that exhibit high polarization values at room temperature in aqueous solutions. Please note that FP is strongly dependent on the temperature and concentration of your fluorophore. Use freshly prepared solutions for each measurement and strictly follow the instructions about storage conditions and how to use these FP standard solutions.
