Semaglutide is the single-agonist reference point most GLP-1 assay work is built around. Here's the mechanism, the formats we stock, and how to verify a lot.
Semaglutide is a GLP-1 receptor agonist modified at position 8 to resist DPP-4 cleavage, with a C18 fatty-acid chain supporting albumin binding. Those two modifications are the reason it appears in nearly every GLP-1 comparison panel.
Structural notes
- Aib substitution at position 8 reduces enzymatic degradation in vitro.
- C18 diacid linker supports extended albumin association.
- Backbone is highly homologous to native GLP-1, simplifying identity confirmation.
Handling
- Store lyophilized vials at -4°F to 46°F (-20°C to 8°C), protected from light.
- Reconstitute with bacteriostatic water; add solvent slowly down the vial wall, never directly onto the pellet.
- Do not shake — swirl gently until fully dissolved.
- Once reconstituted, keep refrigerated and record the reconstitution date on the vial.
- Log the batch/lot number against the matching COA before any assay work begins.
