Product information
GLP-1SG — the compound is a synthetic 31-amino-acid peptide characterized in the receptor-pharmacology research literature as a single-receptor agonist at the glucagon-like peptide-1 receptor (GLP-1R). It is built on the GLP-1(7-37) peptide backbone and incorporates an α-aminoisobutyric acid (Aib) substitution at position 8, and a lipidated lysine at position 26 carrying a C18 fatty diacid via a γGlu-linked hydrophilic spacer — structural features that contribute to its half-life and pharmacokinetic profile as a research tool compound. This product is supplied as a white lyophilized powder at 10 mg labeled size, synthesized by solid-phase peptide synthesis (SPPS) and characterized by HPLC with UV detection (purity) and LC-MS (identity, expected convergent observations at charge states [M+5H]⁵⁺, [M+4H]⁴⁺, and [M+3H]³⁺ back-calculating to ~4113.6 Da). Third-party characterization is performed by Freedom Diagnostics (USA). The product is intended exclusively for in-vitro laboratory research and analytical applications. In the research literature, GLP-1R is referenced as a synthetic GLP-1R agonist used as a tool compound in the study of GLP-1 receptor pharmacology and signaling. Within the True Peptide Labs GLP research family, (GLP-1SG) is the single-receptor member — distinct from the dual-receptor GLP-2TZ (GLP-1R/GIPR) and the triple-receptor GLP-3RT (GLP-1R/GIPR/GCGR) — each characterized as tool compounds in incretin-receptor pharmacology research.
