About Semax as a reference compound
Semax is a synthetic heptapeptide derived from an ACTH fragment, commonly used as a reference compound in neurochemistry and peptide-stability research. PureLabs supplies Semax lyophilized with a full analytical package covering purity, identity, water content and residual solvents.
Handling and storage
- Store at −20 °C; short-term transport at 2–8 °C is acceptable.
- Reconstitute with sterile water or a suitable buffer immediately before use.
- Avoid oxidative conditions that can degrade the peptide sequence.
Semax — frequently asked questions
Common laboratory questions about sourcing, purity, storage and shipping of Semax.
Does the analytical package cover residual solvents?
Yes, the certificate of analysis reports purity, identity, water content and residual solvent levels for each lot.
What form is Semax supplied in?
Lyophilized powder in a sealed vial, with the batch reference printed on the label and matched to an archived certificate of analysis.
How is Semax purity confirmed?
Reverse-phase HPLC establishes purity and mass spectrometry confirms the expected molecular mass, both performed by an independent partner laboratory.
What is the recommended storage temperature for Semax?
−20 °C for sealed lyophilized vials; 2–8 °C for reconstituted solution, used within a few weeks and never refrozen repeatedly.
Is Semax approved for clinical use?
No. PureLabs supplies it purely as an analytical reference compound for laboratory research and it carries no clinical or therapeutic indication.
