Cagrilintide Testing Services

Cagrilintide is a long-acting amylin analog being studied for obesity, often in combination with semaglutide (CagriSema). It modulates appetite and gastric emptying via amylin and calcitonin receptor pathways.

Cagrilintide Testing Methodology

Our analytical workflow for Cagrilintide follows USP <1225> guidance for validated chromatographic methods. Each lot is processed by a credentialed analyst with documented chain of custody.

  1. Step 1

    Sample intake & chain of custody

    Your Cagrilintide sample (1-2 mg lyophilized) is logged at our Florida lab with a unique ID, photographed, and stored at -20 °C until analysis.

  2. Step 2

    Reverse-phase HPLC purity

    Cagrilintide is dissolved in mobile phase and run on a C18 column with a water/acetonitrile gradient containing 0.1% TFA. UV detection at 214 nm quantifies the main peak and any related impurities.

  3. Step 3

    LC-MS identity confirmation

    An aliquot is analyzed by liquid chromatography-mass spectrometry. The observed monoisotopic mass is compared against the theoretical molecular weight (~3800 g/mol) for Cagrilintide to confirm identity.

  4. Step 4

    Impurity profiling & reporting

    Related substances, truncations, and oxidation products are quantified. Findings are compiled into a signed Certificate of Analysis with chromatograms, mass spectra, and analyst interpretation.

Cagrilintide Purity Notes

Recommended research-grade purity for Cagrilintide is ≥95%. Lot-to-lot variation is common with solid-phase synthesis, so independent verification matters.

Common impurities to watch

  • Truncated sequences from incomplete coupling
  • Deletion peptides missing one or more residues
  • Oxidation of methionine, tryptophan, or cysteine
  • Residual TFA, acetate, or solvent counter-ions
  • Aggregates and dimers from improper storage

What our COA confirms

  • Main peak purity by HPLC area %
  • Observed vs theoretical mass (~3800 g/mol)
  • Named impurities ≥ 0.1% area
  • Net peptide content where applicable
  • Method, column, and instrument metadata

Cagrilintide Handling, Storage & Safety

Guidance below is for laboratory and research personnel only. Cagrilintide is supplied for research use and is not intended for human or veterinary use.

Storage

Store lyophilized Cagrilintide at -20 °C, protected from light and moisture. After reconstitution, aliquot and store at -80 °C; avoid repeated freeze-thaw cycles.

Reconstitution

Reconstitute in bacteriostatic or sterile water in a clean environment. Allow vials to reach room temperature before opening to prevent moisture condensation on the powder.

PPE & shipping

Handle with gloves, lab coat, and eye protection. Ship samples to ACS overnight on dry ice or cold packs in a rigid, leak-proof container with a packing slip referencing your quote.
