Technical specifications
- Type
- Peptide
- Scientific name
- 2-Methylalanyl-L-histidyl-3-(2-naphthyl)-D-alanyl-D-phenylalanyl-L-lysinamide (Aib-His-D-2-Nal-D-Phe-Lys-NH2)
- Amino acids
- 5
- Molecular weight
- 711.9 g/mol
- Formula
- C38H49N9O5
- CAS
- 170851-70-4
- Origin
- Synthetic pentapeptide GHS-R1a agonist developed at Novo Nordisk as NNC 26-0161; residue sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2 contains non-proteinogenic residues, so it has no valid one-letter code.
- Lyophilized (powder)
- -20°C, protected from light and moisture · stable long-term; -80°C for multi-year storage
- Reconstituted
- 2-8°C in sterile bacteriostatic or acetate buffer · use within 30 days; aliquot to avoid repeated freeze-thaw cycles
- Room temperature
- Lyophilized powder tolerates brief ambient excursions during shipping, but sustained room-temperature storage is not appropriate — the C-terminal lysinamide and the His residue make the peptide susceptible to hydrolysis and oxidation, and reconstituted solutions left at room temperature degrade within days.
