Product Detail

1. Product Introduction

Retatrutide RT20 is a synthetic modified polypeptide composed of 39 amino acid residues with fatty acid side chain modification.

CAS No.: 2381089-83-2

Laboratory research focuses on its binding characteristics with target receptors and related intracellular biochemical signals within cell model systems. All research results are limited to in-vitro laboratory environments.

This product is supplied as lyophilized powder for laboratory research only. It shall not be used for human administration, clinical trials or any medical application.

2. Product Characteristic Features

Retatrutide RT20 adopts standardized solid-phase synthesis and HPLC purification process. Fatty acid side chain modification effectively improves molecular stability and anti-enzymatic degradation ability.

The finished lyophilized powder possesses good water solubility. Vacuum freeze-drying technology slows molecular degradation and maintains structural stability during transportation and low-temperature storage.

3. Main Research Application Directions

Only for laboratory in-vitro experimental research:

Basic research on polypeptide and target receptor binding characteristics
Exploration of polypeptide structural modification influence on molecular stability
Cell model research of polypeptide mediated intracellular signal transduction
Stability comparison research of modified long-chain synthetic polypeptide under different culture environments
Biochemical exploratory study of polypeptide molecular interaction properties

4. Specifications & Quality Standard

Appearance: White or off-white lyophilized crystalline powder
Purity: ≥98% (HPLC high performance liquid chromatography detection)
Solubility: Freely soluble in sterile purified water and neutral PBS buffer
Moisture content: ≤2.0%
Quality control: Each batch provides complete COA test report, including HPLC purity detection and impurity screening
Batch stability: Mature synthesis & purification process ensures consistent quality among batches

5. Packaging & Storage Specifications

Conventional packaging: Vacuum lyophilized vial packaging; customized packaging supported for bulk orders
Packaging advantage: Aseptic sealed light-proof vial, moisture-proof, effectively prevent molecular inactivation
Storage requirement: Sealed storage at -20℃, protected from light and humidity; avoid repeated freezing and thawing
Shelf life: 24 months under specified low-temperature sealed storage

6. Applicable Scenarios

Suitable for university laboratories, biochemical research institutes, cell biology laboratories and polypeptide research groups, applied to basic cell and molecular experimental research.

Important Notice: For laboratory research use only. Not for human consumption or clinical trials.

ECHEMI Editorial Reference

Retatrutide is a novel triple agonist peptide of the glucagon receptor (GCGR), glucose-dependent insulinotropic polypeptide receptor (GIPR) and glucagon-like peptide-1 receptor (GLP-1R). Retatrutide inhibits human GCGR, GIPR and GLP-1R with EC50 values of 5.79, 0.0643 and 0.775 nM, respectively and mouse GCGR, GIPR, and GLP-1R with EC50 values of 2.32, 0.191 and 0.794 nM, respectively. It is an important tool for obesity research.Retatrutide potently activates the GLP-1R signaling pathway to stimulate glucose-dependent insulin secretion through activity at the GIP receptor (GIPR) or the GLP-1R.Retatrutide is a synthetic peptide with glucose-lowering effects. It is an antidiabetic agent against type 2 diabetes (T2D), stimulating insulin and suppressing glucagon secretion in a glucose-dependent manner.Retatrutide was also shown to delay gastric emptying, lower fasting and postprandial glucose concentration, decrease food intake and reduce body weight in patients with type 2 diabetes.
Retatrutide (LY-3437943) was discovered by the American pharmaceutical company Eli Lilly and Company. It is a triple glucagon hormone receptor agonist (GLP-1, GIP, and GCGR receptors) for obesity. The 2024 Lasker~DeBakey Clinical Medical Research Award has been given to Joel Habener and Svetlana Mojsov for their discovery of a new hormone GLP-1(7-37) and to Lotte Knudsen for her role in developing sustained acting versions of this hormone as a treatment for obesity.
