Nε,Nε,Nε-Trimethyllysine-d₉ chloride  (Synonyms: Ne-(Trimethyl)-L-lysine-d₉ chloride; H-Lys(Me)3-OH-d₉ chloride)

Nε,Nε,Nε-Trimethyllysine-d₉ (chloride) is the deuterium labeled Nε,Nε,Nε-Trimethyllysine (chloride)[1]. Nε,Nε,Nε-Trimethyllysine chloride serves as a precursor for gut flora-dependent formation of N,N,N-trimethyl-5-aminovaleric acid (TMAVA)[2].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

*In solvent : -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture)

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
