Selank

Description

Selank is a synthetic heptapeptide reagent stocked for laboratories and independent investigators sourcing research peptides in Canada. It is supplied as a lyophilized powder in a sealed 10 mg vial, ready for reconstitution in a solvent appropriate to your protocol, and it sits in our cognitive and neuro category alongside other peptides used in neurological and behavioural research models. It is a laboratory material only, sold for in-vitro and preclinical research by qualified buyers.

Overview

Selank is a tuftsin-derived heptapeptide, structurally an analogue of the endogenous immunopeptide tuftsin with a proline-glycine-proline extension that improves its stability relative to the parent fragment. It appears in the neuropeptide literature as a subject of investigation rather than as a therapeutic agent, which is why it is most often ordered by groups working on anxiolytic-type behavioural models, neuropeptide signalling and peptide stability studies. Each vial contains 10 mg of lyophilized peptide, sealed under vacuum and stored cold until it ships. Vials are available singly or as a box of ten for laboratories running longer study arms or repeat assays who would rather draw from one uniform batch than reconcile results across several. Reconstitution solvent is not included, since the appropriate diluent and concentration depend entirely on the assay.

What it is known for

Buyers know Selank primarily as a tuftsin analogue studied in neuropeptide and behavioural research, and they choose this listing for the paperwork behind it. Every batch goes to Janoshik, an independent analytical laboratory, for HPLC purity and mass spectrometry identity confirmation, and the certificate of analysis you receive is matched to the batch in your hand — not a generic document reused across lots. For a short peptide where synthesis by-products and deletion sequences are the realistic risk, that batch-level evidence is what separates a usable reagent from an unknown.

Key features

• Lyophilized 10 mg vial — Freeze-dried peptide is far more stable in transit and storage than a solution, and it lets you set your own concentration rather than working around a supplier’s.
• Third-party HPLC purity testing — Chromatographic purity is measured by an outside lab, not self-reported, so you can see the proportion of target peptide before it enters your assay.
• Mass spectrometry identity confirmation — Confirms the molecular mass matches the intended heptapeptide sequence, ruling out a mislabelled or truncated product before it costs you an experiment.
• Batch-matched certificate of analysis — The COA corresponds to the specific lot you receive, which is what a supervisor, grant auditor or reviewer will ask for when they query your reagent provenance.
• Box of ten option — Keeps a longer study on a single batch, removing lot-to-lot variation as a confounding variable and reducing repeat ordering mid-project.
• Cold storage and cold-chain handling — The peptide is held cold before dispatch rather than sitting at ambient temperature, protecting integrity from our freezer to your bench.
• Shipped domestically from Canada — Avoids customs holds and long uncontrolled transit that expose peptides to heat and delay — orders travel tracked within the country.
• Discreet tracked packaging — Deliveries arrive without external product identification, and tracking lets you plan to receive and refrigerate the vial promptly on arrival.

Benefits

• You can verify what you received against independent analytical data instead of trusting a label.

Specifications

Typical applications

• In-vitro neuropeptide and receptor-level research

Important information

• Refrigerate or freeze the sealed vial on arrival and keep it protected from light; lyophilized peptide is stable far longer than reconstituted material.
• Reconstitution solvent is not supplied — select a diluent suited to your assay and prepare under appropriate aseptic technique.
• Once reconstituted, store cold, minimize freeze-thaw cycles and consider aliquoting to preserve the remainder of the vial.
• Request or download the certificate of analysis for your lot and check that the batch number matches the vial before recording it in your methods.
• If you are running a multi-arm or long-duration study, order the box of ten so all work draws from one batch.
• This product is not a drug, supplement, food or cosmetic. It is not intended to diagnose, treat, cure or prevent any disease and is not for human or veterinary ingestion or administration.

Common questions

What form does Selank arrive in?

A sealed vial of lyophilized (freeze-dried) powder containing 10 mg of peptide. It requires reconstitution in a research-appropriate solvent before use; no diluent is included.

Who performs the testing?

Janoshik, an independent third-party analytical laboratory. They run HPLC for purity and mass spectrometry for identity, and the resulting certificate of analysis is tied to the batch you receive.

What is the difference between the single vial and the box of ten?

Both contain the same 10 mg lyophilized vials. The box of ten is intended for longer or larger studies where keeping every sample on one batch removes lot variation as a variable and saves reordering partway through.

How should I store it?

Keep the unopened vial cold and out of light. After reconstitution, store the solution cold, avoid repeated freeze-thaw cycles, and aliquot if you will be drawing from it over time.

Does it ship from within Canada?

Yes. Pure Peptides Canada is Canadian-owned and dispatches from Canada with tracked, discreet packaging nationwide, so shipments are not held at an international border.

Can this be used by or on people or animals?

No. It is supplied strictly for laboratory research by qualified buyers. It is not a drug, supplement, food or cosmetic, and it is not for human or veterinary use.

In summary

A tuftsin-analogue heptapeptide supplied the way a research reagent should be: lyophilized in a 10 mg vial, independently tested for purity and identity, documented with a certificate of analysis matched to your batch, and shipped cold and tracked from within Canada. Single vials for exploratory work, boxes of ten when a study needs to stay on one lot.
