GLP-3 RT

7x tested

GLP-3 RT is a synthetic research peptide engineered to engage three incretin-family receptors — GLP-1, GIP and glucagon — from a single molecule. It is supplied in lyophilized form, ≥99% analytical purity, for in-vitro and laboratory research into metabolic signaling.

What is GLP-3 RT?

Within the Rejuven8 designation system the numeral says how many receptor targets a compound engages: GLP-1 SM acts at a single incretin receptor, GLP-2 TZ at two, and GLP-3 RT at three. The “RT” suffix identifies the specific triple-receptor research compound in the series.

You will see the name written several ways — GLP3 RT, GLP-3RT, GLP 3 RT, or simply GLP-3 — in search queries, forum threads and supplier listings. They all refer to the same compound. On this page and on our Certificates of Analysis it is GLP-3 RT.

GLP-3 RT is studied as a reference material for how simultaneous activity at the GLP-1, GIP and glucagon receptors behaves compared with single- and dual-receptor agonists. It is supplied strictly for laboratory research.

Research Overview

Researchers investigate GLP-3 RT to understand what a third receptor — the glucagon receptor — contributes to metabolic signaling beyond GLP-1 and GIP receptor activation. Areas commonly explored in experimental models include:

• triple GLP-1 / GIP / glucagon receptor signaling pathways
• glucose-dependent insulinotropic mechanisms
• hepatic glucagon receptor signaling and substrate utilization
• energy balance and nutrient partitioning models
• receptor trafficking, desensitization and signaling bias
• comparative studies against single- and dual-agonist reference compounds

These studies focus on how engineered multi-receptor analogs influence biological pathways involved in metabolic regulation.

Mechanistic Research Insights

GLP-3 RT is characterised in the literature as an imbalanced triple agonist: the three receptors are not engaged with equal potency, and that asymmetry is itself a subject of study. Reported characteristics include:

• measurable activity at the GLP-1, GIP and glucagon receptors from one sequence
• potency at each receptor that differs from the corresponding native ligand
• signaling biased toward cAMP accumulation
• DPP-4 resistance conferred by non-natural residue substitution near the N-terminus
• extended half-life in preclinical models via a fatty-diacid conjugate that binds albumin

Storage

Store lyophilized vials in a cool, dry environment away from direct light: refrigerated (2 to 8 °C) for short-term storage, −20 °C for long-term. Keep sealed and desiccated until use. Reconstituted solutions have their own stability window and should be handled per your laboratory’s protocol.

Frequently Asked Questions

Is it GLP-3, GLP3, GLP-3 RT or GLP3 RT?

Same compound. “GLP-3 RT” is the designation we use on the label and the Certificate of Analysis; the other spellings are how people type it. If a listing elsewhere drops the “RT”, check the sequence and the COA rather than the name.

How is GLP-3 RT different from GLP-2 TZ and GLP-1 SM?

By receptor count. GLP-1 SM engages the GLP-1 receptor; GLP-2 TZ engages GLP-1 and GIP; GLP-3 RT engages GLP-1, GIP and the glucagon receptor. Researchers comparing single, dual and triple agonism in the same assay typically run all three. Our GLP-3 RT receptor signaling overview goes into the pharmacology.

What does the Certificate of Analysis show?

HPLC purity, mass-spectrometry identity confirmation and net peptide content for the specific batch, from an independent laboratory. Match the batch number on your vial to the report in the COA library.

How should lyophilized GLP-3 RT be stored?

Sealed, dry, away from light; refrigerated short-term, frozen at −20 °C long-term. Avoid repeated freeze–thaw of reconstituted material; aliquot if your protocol requires multiple draws.

What is used to reconstitute it in the laboratory?

Lyophilized peptides are brought into solution with a laboratory-grade solvent chosen for the application. For multi-session research workflows that is usually bacteriostatic water; preservative-free sterile water is used where a protocol requires it. We do not provide usage or dosing guidance.

Which vial sizes are available?

Several lyophilized masses — select the size above. Every size is tested the same way and carries its own batch COA.

Is GLP-3 RT for human use?

No. GLP-3 RT is supplied strictly for laboratory research. It is not for human consumption, therapeutic or veterinary use, and not for any form of self-administration.
