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“.

“Our collective group has been involved in developing renal, intravital, 2-Photon imaging since the late 90’s. Throughout the course of this development we have used numerous fluorescent compounds to assess function and investigate morphology. Dextrans of various molecular weights have been employed to study physiologic processes such as fluid phase endocytosis, RBC flow/vascular perfusion, and barrier permeability in the renal vasculature to name a few. In the latter, it is crucial to start with compounds that are narrowly dispersed because dextrans and polysucroses with a broad size distribution will produce permeability values that are time dependent; particularly in injury and disease states. TdB has consistently provided us with compounds of exceptional size characteristics with which to conduct our studies. When I was approached by Charlotte and Tony to help them develop newer probes better suited for intravtial imaging I was delighted to accept. Their larger MW products in particular have proven crucial in correctly interpreting permeability data and will be a great benefit to this burgeoning and growing field.”

“As a CDMO specialized in Biologics and Advanced Therapies, we approached TdB Labs AB to obtain their Dextran sulfate 8HS Pharma grade product as we planned to use it in different upstream processes (USP) for culturing cells. We found the product from TdB Labs to be of utmost quality that has facilitated various projects, thereby enabling us to serve diverse customers. At the same time, we greatly appreciate the technical support provided by them during the entire process.

  • Klosterfrau Berlin

Within the collaborations of Farco Pharma, Purenum GmbH and Klosterfrau Berlin as a production site, we have successfully transferred the innovative sterile medical device mediNiK®. This product is used for the removal of kidney stones and stone fragments, and it contains Blue dextran from TdB Labs that allows us to distinguish clearly and safely between the medical device and the surrounding mucosa. The collaboration with TdB Labs for manufacturing a customized product has been very professional. Timelines were met with high standards even when Blue dextran was needed in large quantities.
