Selank is a synthetic heptapeptide analogue of the endogenous peptide tuftsin, supplied as a lyophilised powder for in-vitro laboratory research. It is used in the scientific literature as a model peptide in investigations of neuropeptide signalling pathways, peptidase stability, and receptor-binding assays. Each batch is verified by RP-HPLC for purity and mass spectrometry for identity, with a batch-specific Certificate of Analysis.
Research Use Only. Intended strictly for in-vitro laboratory research. Not a drug, food, or cosmetic; not for human or animal consumption, diagnosis, treatment, or therapeutic use. Sold only to qualified, verified researchers.

For laboratory handling only. Reconstitute the lyophilised powder by adding the chosen research-grade solvent (e.g. sterile or bacteriostatic water) slowly against the inside wall of the vial; do not inject directly onto the powder. Swirl gently until fully dissolved — do not shake or vortex vigorously, as agitation can degrade peptide material. Calculate the solvent volume to reach the concentration required for your assay. Aliquot to minimise freeze–thaw cycles. Store the reconstituted solution refrigerated and use within approximately 6 weeks. All handling should be performed by qualified laboratory personnel under appropriate conditions.
