Medchemexpress LLC L-Valine-13C5,15N | 202407-30-5 | 123.10 | 100 MG
L-Valine-13C5,15N is the 13C- and 15N-labeled form of L-Valine. It has been shown to cause lipid peroxidation and accumulation of malondialdehyde (MDA), and exhibits inhibitory activity against cyanobacteria. It also inhibits multidrug-resistant bacteria through activation of the PI3K/Akt signaling pathway and inhibition of arginase. This compound is intended for research use only.
- Can be used as a tracer
- Can serve as an internal standard for quantitative analysis using techniques like NMR, GC-MS, or LC-MS
- Incorporates stable heavy isotopes of carbon (13C) and nitrogen (15N), useful for quantitation during drug development processes
