Alkali Scientific Choline Chloride, 500 Grams
Choline Chloride is a quaternary ammonium salt widely used in cell culture, biochemical research, and nutritional studies. It serves as an essential nutrient involved in membrane structure and lipid metabolism, particularly as a precursor for phosphatidylcholine synthesis. In cell culture applications, choline chloride supports cell growth and viability by contributing to membrane integrity and signaling pathways. It is also used in metabolic research to study neurotransmitter synthesis and methyl group metabolism. The compound is commonly incorporated into media formulations and biochemical assays, providing a stable and water-soluble source of choline for laboratory and research applications.

D13-9001 is a small-molecule inhibitor of RND-family bacterial efflux pump subunits AcrB (AcrAB-TolC) and MexB (MexAB-OprM). It shows binding affinities (KD ≈ 1.15 μM for AcrB and 3.57 μM for MexB) and is used in microbiology research to study efflux-mediated antibiotic resistance and to potentiate antimicrobial agents in vitro. The compound is supplied as a high-purity solid suitable for biochemical and cellular assays.
- Potent inhibitor of AcrB and MexB efflux pump subunits.
- Measured KD values near 1.15 μM (AcrB) and 3.57 μM (MexB).
- High reported purity suitable for biochemical assays.
- Solid small-molecule formulation amenable to in vitro testing.
- Useful for research on efflux-mediated antibiotic resistance and potentiation assays.
