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.

Plants live in close relationships with complex populations of microorganisms, including rhizobacterial species commonly referred to as plant growth-promoting rhizobacteria (PGPR). PGPR are able to improve plant productivity, but the molecular mechanisms involved in this process remain largely unknown. Using

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

The present study aims at predicting the level of formation of the ultimate carcinogenic metabolite of methyleugenol, 1'-sulfooxymethyleugenol, in the human population by taking variability in key bioactivation and detoxification reactions into account using Monte Carlo simulations. Depending on the
