About this material

What it is

The reduced tripeptide thiol, supplied lyophilised under nitrogen at a 200 mg fill. Released at 99.8% with residual water at 0.9%. Because the reduced form oxidises readily on air exposure, the certificate records both the release figure and the date of test so the interval between release and your own retest is on the record.

Laboratory handling

Storage and material handling

  1. 01Equilibrate the sealed vial to ambient temperature before breaking the seal.
  2. 02The reduced form oxidises on air exposure. Reseal under inert gas if the vial is to be re-entered.
  3. 03Residual water released at 0.9% — the driest item in the catalogue. Keep it that way.
  4. 04Dispose of unused material and rinsate according to your institution's chemical waste procedure.

Laboratory storage and material handling only. No dose, concentration, route, frequency or administration guidance is provided for this or any other item, for humans or animals.

Would not speculate, and said so

I asked a question that was really about application rather than material, and the reply said support cannot advise on protocol or use and pointed me back to the certificate and the release date. Correct answer. I have had suppliers cheerfully invent one.
