Selank is a synthetic regulatory heptapeptide engineered by conjugating the naturally occurring tetrapeptide Tuftsin (Thr-Lys-Pro-Arg) to a metabolic stabilizing tripeptide sequence (Pro-Gly-Pro) at its carboxy terminus. This structural elongation confers enhanced enzymatic resistance against aminopeptidases and carboxypeptidases while modifying its neurotropic profile. It is supplied strictly for in vitro allosteric GABA receptor modulation assays, monoamine neurotransmitter metabolism studies, brain-derived neurotrophic factor (BDNF) expression kinetics, and laboratory neuro-immunomodulatory pathway modeling in cell cultures. Supplied as a stable lyophilized powder suitable for analytical reconstitution.
