How the molecule is built
Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH. An acetylated norleucine opens the chain, followed by a six-residue ring that an amide bond closes between the side chains of aspartic acid and lysine. One residue, D-phenylalanine, is a D-amino acid.
What comes with each batch
- Certificate of analysis from the manufacturer, showing the batch number, the HPLC purity and the identity by mass spectrometry.
- Batch number and expiry date on the vial, on the box and on the delivery note.
- Safety data sheet: on request, where the manufacturer issues it.
The certificate for your batch comes with the goods. Each line of a certificate is explained in how to read a certificate of analysis.
Storage on arrival
Keep it at the condition printed on the label. Until the vial is needed, leave it sealed, dry and out of the light. The reasoning is set out in our peptide storage guide.
