§ About Selank

Selank is a synthetic heptapeptide derived from the tuftsin peptide sequence and extended with a Pro-Gly-Pro motif. Its sequence is Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP).

Published research has examined Selank in neurochemical, gene-expression and behavioural models. Much of the mechanistic literature is experimental or preclinical, so findings should not automatically be represented as established human effects. PepDirect supplies Selank exclusively for laboratory research use.

§ FAQ

What is Selank?: Selank is a synthetic heptapeptide derived from the immunomodulatory peptide tuftsin, extended with a C-terminal Pro-Gly-Pro motif. It is investigated in neurochemical and behavioural research models.
What is the Selank peptide sequence?: Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP).
How is Selank related to tuftsin?: The N-terminal portion of the Selank sequence corresponds to the tuftsin tetrapeptide (Thr-Lys-Pro-Arg). Selank extends that sequence with a Pro-Gly-Pro motif intended to improve enzymatic stability.
What areas of research involve Selank?: Reported research areas include neurochemical signalling, gene-expression research, experimental GABA-system studies and stress-response behavioural models in animals.
What is the difference between Selank and Semax?: Semax and Selank are both synthetic heptapeptides originating from Russian neuroscience research, but they have different sequences (MEHFPGP vs TKPRPGP), different research origins (ACTH-fragment-related vs tuftsin-related) and different research literatures. See the Semax vs Selank comparison guide for a full side-by-side.
How is PepDirect Selank tested?: Every lot is supplied with lot-specific documentation. HPLC purity is reported on the product hero and full identity information is captured in the lot Certificate of Analysis.
How is PepDirect Selank tested?: Selank is tested by HPLC to a purity of ≥ 99.5%. The current lot displayed on this page is TM-2499. A lot-specific Certificate of Analysis is published on the product page before purchase and ships in the box.
Is this intended for human use?: No. All PepDirect products are sold strictly for laboratory and research use only, and are not intended for human or veterinary use, consumption, or any clinical or diagnostic application.
How quickly does PepDirect ship?: Orders placed before 3:00 PM GMT are dispatched the same business day. Orders placed after 3:00 PM GMT are dispatched the next business day, with tracked delivery in 1-2 business days across the UK and EU. Shipping is calculated and shown at checkout based on destination.
Does PepDirect provide a Certificate of Analysis?: Yes. Every lot's COA is published on the product page before it ships, and the same PDF is included in the box.
What is your guarantee?: Same-day replacement on damaged or lost shipments, or a full refund on request, no questions asked.
