What is FR5 ?

FR5 is catalog designation, 5 mg per vial. It is manufactured via solid‑phase peptide synthesis and presented as white lyophilized powder with tested purity ≥98%.

In laboratory studies, FR5 is applied for in‑vitro and pre‑clinical experiments including cellular lipid metabolism assay, energy‑related signaling exploration, adipocyte biological characteristics and metabolic‑biology associated biological‑model research. This item is lab‑grade research raw material only for biochemistry, molecular‑cell and pharmacology research projects..

Store unopened lyophilized powder at ‑20℃, keep dry and away from light. Reconstitute with 0.9% BAC bacteriostatic water. After reconstitution, store at 2‑8℃ refrigeration. Gently swirl the vial to dissolve powder, do not shake violently. Avoid repeated freeze‑thaw cycles, aliquot is recommended for dissolved peptide solution.

Research

Class:

GLP-1R agonist

Status:

FDA-approved (Ozempic / Wegovy / Rybelsus)

Mechanism:

Long-acting, selective glucagon-like peptide-1 (GLP-1) receptor agonist with 94% sequence homology to human GLP-1. Engineered for extended half-life (~1 week) via albumin binding (fatty acid acylation at Lys26) and resistance to DPP-4 degradation (Aib substitution at position 8). Promotes insulin secretion, inhibits glucagon release, delays gastric emptying, and reduces appetite via central nervous system GLP-1R activation.

Activity note:

Potent, selective GLP-1R agonist. Reported binding affinity Ki = 0.38 ± 0.06 nM. Semaglutide is a human GLP-1 analog with structural modifications for albumin binding (C18 fatty diacid at Lys26) and enzymatic stability (Aib8 substitution).
