What is Semax?
Semax is a laboratory research material used to examine peptide signaling, receptor-linked pathways, and cellular-response behavior in controlled experimental models. References to biological effects are provided for scientific context only and must not be interpreted as claims of therapeutic, diagnostic, or clinical benefit. This product is not offered for human or veterinary use.
Semax is a synthetic heptapeptide built from the ACTH(4-10) fragment extended at the C-terminus with a Pro-Gly-Pro tripeptide. The added tripeptide is the structural feature that distinguishes it from the parent fragment and is described in the literature as increasing resistance to peptidase cleavage.3
Why is Semax studied?
Research interest is in the peptide as a probe for neurotrophin regulation: unlike the parent ACTH fragment it has been examined for effects on the expression of brain-derived neurotrophic factor and its receptor, which makes it a tool for studying that signalling axis.3, 4
How is Semax studied in the lab?
Published work uses rat hippocampal tissue and primary rat glial cell cultures. Readouts are mRNA levels measured by reverse-transcription PCR and protein levels measured by immunoassay, sampled at defined intervals after exposure.3, 4
What has preclinical research reported?
Research Context
In laboratory research, Semax is examined for its interaction with cellular signaling systems and downstream experimental readouts. Studies may focus on receptor-mediated responses and molecular pathway behavior in controlled research environments. These references are included solely for scientific context and should not be interpreted as claims of medical benefit.
Selank : Research Areas

All references to biological pathways are provided for research context only and do not imply human or veterinary applications.
BDNF and trkB expression (rat hippocampus)
In rat hippocampus the peptide was reported to regulate expression of brain-derived neurotrophic factor and its receptor trkB, measured at the transcript and protein level.3
Neurotrophin mRNA induction (rat glial cultures)
In primary rat glial cell cultures, rapid induction of neurotrophin mRNAs was reported following exposure to the ACTH analogue.4

|---|---|
| Lyophilized, short term | Room temperature is usually adequate for several weeks; refrigeration under 4°C (39°F) is generally acceptable |
| Lyophilized, long term | Freezer at -80°C (-112°F) for several months to years |

| Light and moisture | Keep cold and away from light in the original sealed vial |
Why the powder is stable
All of our products are manufactured using the lyophilization (freeze drying) process, which keeps them stable for shipping for up to 3–4 months.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until it is reconstituted with bacteriostatic water.
Storing vials on arrival
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used in the next several days, weeks or months, short-term refrigeration under 4°C (39°F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
For longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80°C (-112°F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
After reconstitution
Once the peptides are reconstituted with bacteriostatic water, they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
