Medchemexpress LLC Tcep-d16 hydrochloride | 1174025-33-2 | 97.0% | 302.75 | 5 MG
TCEP-d16 (hydrochloride) is the deuterium labeled TCEP hydrochloride. TCEP hydrochloride (Tris(2-carboxyethyl)phosphine hydrochloride) is a non-thiol reducing agent that is more stable and produces a faster S-S reductive reaction than other chemical reductants. TCEP hydrochloride is a trialkylphosphine, selectively reduces protein disulfides without altering the properties or interacting with thiol-directed agents in the reaction mixture. TCEP hydrochloride is also a commonly used reducing agent in the DNA/AuNP chemistry.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
