About this compound

Glutathione (γ-L-glutamyl-L-cysteinylglycine) is a tripeptide in which glutamate is joined to cysteine through its side-chain (γ) carboxyl group rather than the usual α-carboxyl. Its free cysteine thiol is prone to oxidation, so sealed storage matters. Supplied as a lyophilized powder in a sealed glass vial for laboratory research and analytical use.

What you receive

One sealed vial of lyophilized compound, labeled with its lot number. The batch COA is in our COA Library.

Not sold or supplied

Syringes, needles or usage instructions. RWP Laboratories sells research materials only.

HPLC chromatogram, mass spectrum, lot COA

Reference values from public chemical databases. The certificate of analysis for your lot is the authority for that vial.

Storage and handling

Store cold

Sealed vials at 2 to 8 °C (36 to 46 °F), protected from light, as printed on the label. Freeze at −20 °C for long-term storage.

Warm before opening

Let cold vials reach room temperature to prevent condensation on the powder.

Keep sealed

Store in the original sealed vial, dry and away from light, until the material is needed.

More detail in our storage and handling guide.

Questions

Does Glutathione ship with a certificate of analysis?

Yes. Every lot is tested for identity by mass spectrometry and purity by HPLC before release. The lot number on your vial matches its COA in our COA Library.

How should Glutathione be stored?

Keep sealed vials refrigerated at 2 to 8 °C (36 to 46 °F) and protected from light, as printed on the label. For long-term storage, freeze at −20 °C. Let a cold vial reach room temperature before opening. See our storage guide.

Does Glutathione come with syringes or needles?

No. RWP Laboratories does not sell or supply syringes or needles, and does not provide usage instructions.
