General description
Potassium phosphate solution have very high buffering capacity that is widely used in molecular biology, biochemistry, and chromatography. Potassium phosphate dibasic trihydrate is a key component of potassium phosphate buffer, phosphate-buffered saline (PBS), and phosphate-buffered EDTA (PBE). It is extensively used in the preparation of biological samples for various biological experiments. Potassium phosphate buffer is also used in methods such as equilibrium dialysis, high-performance liquid chromatography (HPLC), and affinity capillary electrophoresis (ACE) to study the characteristics of drug-protein interactions in the body. Potassium phosphate buffer solutions consist of mixtures of the potassium phosphate monobasic and potassium phosphate dibasic forms.
Application
Potassium phosphate dibasic trihydrate has been used in the preparation of potassium phosphate buffer for the resuspension of polyelectrolyte capsules. It has also been used as a buffer during glutaminase‑1 (GLS-1) enzyme assay and GLS-2 enzyme assay.

Polyelectrolyte hollow capsules are versatile platforms typically used for encapsulation of a wide variety of macromolecules in their cavity. The polymer shell of these capsules as composed by alternating layers of oppositely charged polyelectrolytes also allows for adding additional functionalities.

Inhibition of glutaminase-1 (GLS-1) hampers the proliferation of tumor cells reliant on glutamine. Known glutaminase inhibitors have potential limitations, and in vivo exposures are potentially limited due to poor physicochemical properties. We initiated a GLS-1 inhibitor discovery program focused on
