Selank in research
Selank is a synthetic heptapeptide based on the tuftsin sequence with a Pro-Gly-Pro extension. Research use focuses on peptide stability, peptidase resistance, and neuroimmune pathway markers in laboratory models.
Sequence-specific QC
The Pro-Gly-Pro tail is verified in MS identity data and HPLC purity is reported at the lot level. Net peptide content supports accurate preparation of assay stocks.
Storage and handling
Store sealed lyophilized vials at -20 °C, protected from light. Reconstitute with bacteriostatic water, aliquot, and freeze working stocks.
Documentation
CoA covers identity, purity, and net peptide content. Batch records are filed by SKU and lot.
Research guide
Selank research overview
Selank is listed as a research-use-only material for qualified laboratory programs. This page connects the product listing with identity fields, storage context, CoA review, and long-form research resources so procurement and QA reviewers can evaluate the SKU without relying on a thin commerce page.
The catalog classifies this material as Tuftsin-derived peptide (research), which helps labs compare it with adjacent research peptides, organize internal inventory, and build study-specific reference groups.

Storage and handling context
For long-tail stability searches, Selank should be evaluated in the context of lyophilized storage, reconstitution buffer choice, aliquot planning, freeze-thaw limits, and lot-specific CoA conditions. Always follow institutional SOPs and the documentation attached to the received lot.
Mechanism context
Selank should be described through published model-system language: receptor family, pathway context, assay controls, concentration planning, and lot traceability. Avoid transferring assumptions from adjacent peptides without a documented comparison protocol.

Product FAQ
Is Selank intended for clinical programs?
No. BluGen listings are research use only (RUO) materials for qualified laboratory programs, not clinical, diagnostic, therapeutic, veterinary, food, drug, or cosmetic use.
What documentation is available for Selank?
Lot-level documentation may include CoA, HPLC purity, MS identity confirmation, net peptide content, and batch records where available for the SKU and lot.
How should lyophilized Selank be stored?
Store sealed lyophilized vials cold, dry, and protected from light unless the lot CoA or institutional SOP specifies another condition. Reconstituted material should be aliquoted according to the lab protocol.
Where can I learn more about Selank research context?
See the BluGen research guide for mechanism context, stability notes, storage considerations, and related peptide comparisons: https://getblugen.com/research/research-guide-selank/
What is the research category for Selank?
Selank is categorized as Tuftsin-derived peptide (research) for catalog organization, internal linking, and related research comparisons.
What sequence is listed for Selank?
The listed sequence for Selank is Thr-Lys-Pro-Arg-Pro-Gly-Pro. Always verify sequence and identity against the lot-specific CoA before use in a research workflow.
What molecular weight is listed for Selank?
The listed molecular weight for Selank is 751.88 g/mol. Use the lot CoA and net peptide content when calculating research stock concentrations.
Does Selank require cold storage?
Most lyophilized research peptides are stored cold, dry, sealed, and protected from light unless the lot CoA or institutional SOP states otherwise.
How should reconstituted Selank be handled?
Reconstituted research stocks should be labeled with SKU, lot, solvent, concentration, date, and technician initials, then aliquoted according to the lab protocol to limit freeze-thaw history.
Can lots of Selank be mixed together?
Avoid mixing lots unless a written protocol requires it. Mixed-lot stocks reduce traceability and make CoA review more difficult.
What purity documentation matters for Selank?
HPLC purity, MS identity, net peptide content, moisture or residual summaries where available, and lot number alignment are the core documentation checks.
What does net peptide content mean for Selank?
Net peptide content accounts for peptide mass apart from water and counter-ion contribution. It is important for molarity calculations in laboratory records.
What should procurement review before ordering Selank?
Procurement should review SKU, vial size, lot documentation path, RUO status, storage requirements, shipping expectations, and any internal approval requirements.
How should Selank be cited in a method record?
Record supplier, SKU, lot number, CoA document ID, reconstitution solvent, stock concentration, storage condition, and date prepared.
What are common related resources for Selank?
Related resources include the peptide storage guide, reconstitution guide, CoA reading guide, purity guide, and any comparison articles linked from the product page.
Why does BluGen link Selank to research articles?
Internal article links help buyers evaluate identity, storage, documentation, and research context without relying on a thin product listing.
What should be done if Selank documentation is incomplete?
Hold the lot in review and request the missing CoA or batch documentation before releasing the material into an internal research workflow.
Is Selank content on BluGen medical advice?
No. BluGen content is laboratory procurement and research documentation content for RUO materials only.
