Purity > 98 % Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Anion-exchange FPLC.
(c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.
Add. information Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm.
2. Analysis by RP-HPLC, using a standard solution of GHRP-2 as a Reference Standard.
Background GH-releasing peptides (GHRPs) are synthetic peptides that like GHRH act directly on pituitary somatotrophs to stimulate GH release. GHRP-2, an investigational drug, is one of the most potent members of the GHRP family. It has been shown to be effective in adults via the oral and intranasal as well as the iv route of administration.

6. Growth hormone-releasing peptide-2 reduces inward rectifying K+ currents via a PKA-cAMP-mediated signalling pathway in ovine somatotropes.
J Physiol 2002 Dec 1;545(Pt 2):421-33.
Storage Lyophilized GHRP-2 although stable at room temperature for 3 weeks, should be stored desiccated below -20°C.
Upon reconstitution GHRP-2 should be stored at 2-8°C between 2-7 days and for future use below -20°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Shelf life: One year from despatch.
Synthetic GHRP-2 is a single, non-glycosylated polypeptide chain containing 6 amino acids, having a molecular mass of 746.9 Dalton and a Molecular formula of C42H50N8O5.
AA Sequence:
Amino Acid Composition: H-D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2
Less than 1% as determined by silver-stained SDS-PAGE gel analysis.
>98% Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Anion-exchange FPLC.
(c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.
Sterile filtered white lyophilized (freeze-dried) powder without additives
It is recommended to reconstitute the lyophilized GHRP-2 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
