Why these compounds are studied together

Semax is a heptapeptide analogue of ACTH(4-10) studied for BDNF and neurotrophin expression in neuronal cultures.
Selank is a tuftsin-derived heptapeptide studied for GABAergic and enkephalinase-related signalling.
DSIP (delta sleep-inducing peptide) is a nonapeptide used in neuroendocrine signalling models.

Bench handling notes

Short peptides adsorb to glass and some plastics at low concentration; carrier protein or low-bind tubes help.
Prepare neuronal-culture stocks in the same medium used for the vehicle control.

Laboratory handling only. See the research blog for storage, reconstitution and COA guides.
