Endocrine & Neuropeptide Research

What does this category cover?

Neuropeptides are made and released by neurons and act mainly through G protein-coupled receptors (Russo, 2017). This category covers peptides studied in that context, including hypothalamic releasing-hormone analogs and synthetic neuropeptide analogs. Each product page lists molecular formula, molecular weight, CAS number, sequence and primary molecular target, with linked citations.

How is each lot tested?

Every lot is tested by an independent third-party laboratory against the same five-method panel before release: HPLC for purity, with a 98% minimum; mass spectrometry for identity; net peptide content against the label claim; endotoxin by LAL; and appearance. The full certificate for every lot is published in the Astramide certificate library, and each method is explained in how Astramide tests every lot.

How are these compounds stored?

Lyophilized compounds are held at -20°C, protected from light and moisture. Once reconstituted, they are held at 2 to 8°C and used within the window stated on the product page. Repeated freeze-thaw cycles should be avoided.
