Acetylated or not
The acetyl group adds roughly 42 Da. If your protocol specifies N-acetyl Semax, a plain Semax quotation is not the same material, however similar the name looks.
Peptide range · Neuro & cognitive
Neuro & cognitive
peptides.
Neuropeptides and their analogues studied in cognitive, stress-response and neuroprotection models — with the acetylation state documented rather than assumed.
Overview
Small peptides, precise differences.
The range covers Semax and Selank — the Russian-developed analogues of ACTH(4–10) and tuftsin — together with DSIP, the tripeptide PE-22-28, Pinealon, the opioid heptapeptide Dermorphin and vasoactive intestinal peptide.
Acetylation is the trap. N-acetyl Semax is a different molecule from Semax: different mass, different stability, and in the literature, different results. We list both as separate codes so that a quotation cannot quietly substitute one for the other.
- Semax and N-acetyl Semax as separate catalogue items
- Selank (tuftsin analogue) and DSIP supplied as lyophilised powder
- Sequence and MS identity stated per batch
- Cold-chain available where the transit route needs it

Specification
What to specify.
Three things decide whether two quotations for the “same” peptide are actually the same material.
Match the sequence
Several of these peptides exist as fragments of a longer parent. The code, the sequence on the specification and the MS result should all agree with what you asked for.
Handling
Lyophilised neuropeptides are hygroscopic and light-sensitive. Let the vial reach room temperature before opening, and keep it sealed at −20 °C between uses.
