Description
Five milligrams of Selank is enough to set up an HPLC method, confirm solubility in your own buffers and run an initial set of assays before deciding on the larger vial.
Selank 5 mg for a first look
Because the peptide is short, basic and proline-rich, its chromatography benefits from an ion-pairing agent such as trifluoroacetic acid in the mobile phase; without it, peak shape can suffer. That is a useful thing to know before the first injection, and a small vial means the learning costs little material.
The identity table lists formula C33H57N11O9 and CAS 129954-34-3, which together with the sequence are what to record in lab notes alongside the cap and crimp colour.

Questions about Selank 5mg
Why might Selank tail on HPLC?
Basic residues interact with residual silanols on the column. An ion-pairing agent in the mobile phase usually sharpens the peak.
Should I start with 5 mg or 10 mg?
Start with 5 mg if the assay is new to you. Move to 10 mg once conditions are fixed.
How is the vial matched to a certificate?
By the cap and crimp colour recorded on the certificate on our COAs page.
