Questions

What is Selank?
A synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro: the tuftsin tetrapeptide (Thr-Lys-Pro-Arg), an endogenous sequence, extended at its C-terminus by Pro-Gly-Pro. Also written TP-7.
What does 10 mg on the Selank vial mean?
The label states the total quantity in the vial: 10 mg of lyophilized powder. Solara does not publish whether that figure is the gross powder weight or the net peptide content.
What is the molecular weight of Selank?
PubChem lists an average molecular weight of 751.9 g/mol and the formula C33H57N11O9 (PubChem CID 11765600). This is a computed reference value for the compound, not a measurement of a Solara lot. The label does not state the salt form; a salt has a higher formula weight than this value.
What is the CAS number of Selank?
The CAS Registry Number given for Selank in its PubChem record is 129954-34-3; other salt forms carry other numbers.
How should Selank be stored?
Store the sealed vial at −20 °C, protected from light and moisture. Let it reach room temperature before opening.
Where does Solara ship Selank from?
Solara ships from Canada. Orders are dispatched within one to two business days of payment, sealed and packed to keep the powder dry and out of light. Prices are in Canadian dollars. Shipping is $15 flat per order, and free on orders over $200.
Is Solara's Selank for human use?
No. The Selank Solara supplies is a lyophilized powder for laboratory research use only, not for human or veterinary use. This product is not an authorized drug, carries no Drug Identification Number and is not GMP material. The Research use policy states the full condition of supply.
