Documented reference chemistry.
GLP-1, glucagon-like peptide-1, is a 31-residue incretin-class peptide encoded by the proglucagon gene. BF-1S is the semaglutide-class research analog, supplied by BioFusion as a research-reference 5mg lyophilized vial 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.
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).
Storage & handling
Lyophilized BF-1S 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.
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 synthesizes domestically with no offshore re-labeling. Compare with our BF-2T dual-incretin reference and BF-3R triple-incretin reference for cross-class research panels. Bulk discounts trigger at three+ vials; members save 25% on every order.
For research and laboratory use only. This product is not a drug, food, or cosmetic, and is not intended for diagnostic, therapeutic, or in vivo human use.
Keep lyophilized until needed.
Store the lyophilized vial cool and dry, away from light, until your protocol calls for it. In freeze-dried form the material stays stable for extended bench storage.
Reconstitute as needed with the diluent your method specifies, then keep the prepared solution refrigerated and use it within your validated window.
