Sema GLP-1 (5MG)

GLP-1 — glucagon-like peptide-1 — is a 31-residue incretin-class peptide encoded by the proglucagon gene. BioFusion supplies a research-reference 5mg lyophilized vial of the semaglutide-class research analog for incretin-biology and GLP-1-receptor chemistry research.

Research context

GLP-1 has been the most frequently cited incretin reference peptide in research literature since 2020, with publication volume rising rapidly through 2025. The semaglutide-class analog supplied by BioFusion incorporates the structural modifications that extend half-life and enable receptor-binding studies on a research-comparable timescale. The free GLP-1 chemistry primer covers sequence, the GLP-1 vs GLP-2 distinction, and how dual- and triple-incretin analogs differ from the parent compound.

Synthesis & documentation

Produced by solid-phase peptide synthesis using Fmoc protecting-group strategy in a U.S.-based ISO 9001:2008 facility. Each lot is verified for identity (LC-MS), purity (reverse-phase HPLC-UV ≥99.0%), moisture (Karl Fischer titration), and counter-ion content (ion chromatography). The signed Certificate of Analysis ships with every order. The COA reading guide explains every line of analytical data.

Storage & handling

Lyophilized GLP-1 is stable at −20 °C for the printed shelf life. After reconstitution, reference-stability data supports use within fourteen days at 2-8 °C protected from light; avoid freeze-thaw cycling. The BioFusion reconstitution calculator handles vial-volume and working-concentration math for any intended protocol concentration.

Why BioFusion

The incretin-research category is one of the most counterfeited segments online — many third-party listings sell mass-spec-failed batches as “GLP-1.” BioFusion publishes lot synthesis-date and HPLC-purity data on the batch transparency ledger, releases COAs through the COA library, and synthesizes domestically with no offshore re-labeling. Compare with our GLP-2 dual-incretin reference and GLP-3 triple-incretin reference for cross-class research panels. Bulk discounts trigger at three+ vials; members save 25% on every order.
