Overview Tirzepatide (LY3298176) is a 39-amino-acid synthetic peptide engineered as a dual agonist of the GIP and GLP-1 receptors - the two principal incretin receptors. The peptide backbone is derived from the native GIP sequence and includes two 2-aminoisobutyric acid (Aib) residues that confer resistance to DPP-IV degradation, together with a C20 fatty-diacid chain attached at Lys20 that promotes reversible albumin binding and a circulating half-life of roughly five days.[1][4] Native GIP and

How does GLP2-T work? What is its mechanism of action?

Mechanism of Action Dual Incretin Receptor Agonism Tirzepatide is a full agonist at both the GIP receptor and the GLP-1 receptor - class B (secretin-family) Gs-coupled GPCRs expressed on pancreatic beta-cells and alpha-cells, adipocytes, and central-nervous-system neurons involved in appetite regulation. Receptor occupancy elevates intracellular cAMP and activates PKA signaling, which in the beta-cell potentiates glucose-dependent insulin secretion.[4][2] Imbalanced / Biased Agonism Pharmacology

What are the research applications of GLP2-T?

Research Applications Tirzepatide is studied in preclinical and clinical research that probes dual GIP/GLP-1 receptor biology and its downstream metabolic effects. Reported research applications include: Dual-Incretin-Receptor Pharmacology - Used as a high-potency, DPP-IV-resistant co-agonist probe to characterize GIP-receptor and GLP-1-receptor coupling, cAMP/beta-arrestin balance, and receptor desensitization kinetics in recombinant cell-line and primary islet systems.[4] Glucose-Dependent Ins

How should GLP2-T be stored?

Store lyophilized at 2-8C (refrigerated). After reconstitution with bacteriostatic water, store refrigerated (2-8C) and use within 30 days. Do not freeze the reconstituted solution.

Storing GLP2-T: Best Practices

Lyophilized Peptide Storage

Store lyophilized tirzepatide vials at 2C to 8C (36F-46F), protected from light. For long-term storage, keep frozen at -20C. Stable for up to 24 months under recommended conditions. Do not use beyond the expiration date printed on the vial.

Reconstitution

Reconstitute with bacteriostatic water. Add the diluent slowly down the inside wall of the vial and gently swirl - do not shake. Allow the powder to dissolve fully; the reconstituted solution should appear clear and colorless.

After Reconstitution

Store the reconstituted solution refrigerated at 2C to 8C and use within 30 days.

Handling Precautions

Inspect the reconstituted solution visually prior to use. Do not use if it appears cloudy, discolored, or contains particulate matter. Each vial is accompanied by a Certificate of Analysis (COA) detailing purity verification via RP-HPLC and Mass Spectrometry (MS). This product is for research use only (RUO).
