“This spring, I had the opportunity to try out a newly launched pH probe from TdB Labs called FARD20. FARD20 is composed of a dextran molecule with two attached fluorophores: Antonia RedTM, which remains static and FITC, which changes as a function of pH. This gives the FARD molecule a unique fluorescent fingerprint, mapping directly to pH. FARD20 seemed like a great match for many Labbot applications since it unlocks pH readouts in samples where pH electrodes cannot be used, such as the interior of cells, samples that are incompatible with electrode surfaces, or samples with very small volumes.
Conversely, the high precision titration system and full spectrum fluorescent readouts of Labbot made FARD20 very easy to work with, and we could get some very nice titration data almost out of the box. We are always excited when we find systems that complement the Labbot instrument and extend the range of experiments our users can perform. We look forward to our continued exchange of knowledge with TdB Labs to help them achieve the best possible science“.
