Cagrilintide is a long-acting amylin analog that has drawn research interest for its role in metabolic and satiety-signalling pathways, often studied alongside the GLP-1 class. This overview collects what an HPLC-verified lab needs to source, store, and reproducibly handle the reference standard.
What cagrilintide is
Amylin is a pancreatic hormone co-secreted with insulin. Cagrilintide is an engineered amylin analog designed for an extended half-life, which is why it appears in research models exploring long-acting metabolic signalling. It is studied as a distinct mechanism from incretin (GLP-1) agonists, and the two are frequently examined in combination.
Why purity matters here
For a peptide studied at low concentrations in sensitive assays, sub-floor purity introduces confounds that look like real signal. The reproducibility gap on most catalogs comes from one place: lots that don't hit ≥ 99% HPLC purity get sold anyway. Pure North's published floor is 99.0%; every lot carries a Janoshik-verified COA at /lab-results/.
Handling and storage
Treat cagrilintide like other lyophilized reference standards: store dry at −20 °C, reconstitute in sterile bacteriostatic water at your protocol's working concentration, aliquot before freezing, and avoid repeated freeze-thaw cycles. See our reconstitution guide and working-window notes.
Identity confirmation
Because amylin analogs are sequence-engineered, mass-spec identity confirmation is as important as the purity number, it verifies you have cagrilintide and not a near-mass impurity. Both figures appear on the lot COA.
