NA Selank (N-Acetyl Selank) is an acetylated heptapeptide based on the Selank sequence, engineered to improve stability, receptor interaction, and resistance to enzymatic breakdown compared to the original molecule. It is derived from the tuftsin family of peptides and has become a preferred format in modern neuropeptide and cognitive-pathway research :contentReference[oaicite:0]{index=0}. Poly Biotech supplies NA Selank in 5mg and 10mg lyophilized vials with local availability in Colombia.
Selank is a synthetic analogue of the endogenous tetrapeptide tuftsin and is typically described as a seven–amino acid extension with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro :contentReference[oaicite:1]{index=1}. NA Selank introduces an N-terminal acetyl group to this sequence (Ac-Thr-Lys-Pro-Arg-Pro-Gly-Pro), a modification associated with enhanced chemical stability, improved pharmacokinetic profile, and more robust performance in in vitro and preclinical models :contentReference[oaicite:2]{index=2}. By transitioning from standard Selank to NA Selank, Colombian research teams can work with a more advanced, stability-optimised version of the peptide.
NA Selank can be reconstituted using bacteriostatic water or another suitable sterile diluent, according to each laboratory’s internal SOPs. Working concentrations, dilution volumes, and handling procedures should be defined by the research team based on their specific protocols and experimental design.
NA Selank (N-Acetyl Selank) 5mg and 10mg vials are available in flexible quantities for Colombian labs and clinics, including pilot-scale and program-scale orders. Poly Biotech can coordinate recurring shipments and integrate NA Selank into broader peptide procurement plans alongside your existing catalog.

All Poly Biotech peptides are produced using a lyophilization (freeze-drying) process that guarantees product stability during shipping and storage. This process removes moisture under controlled low-pressure conditions, creating a stable white powder that preserves the peptide’s structure and potency.
