Product details Description
Compound Class: Triple Receptor Agonist (GLP-1/GIP/Glucagon) Chemical Structure: Synthetic peptide analog (39 amino acids) Molecular Weight: 4858.4 g/mol Molecular Formula: C223H348N60O68S Form: Sterile lyophilized powder Quantity: Total mg as selected above supplied in a single vial Purity: ≥98% by HPLC analysis Solubility: Soluble in sterile water or phosphate buffered saline Research applications
Multi-receptor binding and activation studies across GLP-1, GIP, and glucagon receptors Comparative pharmacology of single vs. multi-agonist peptides Signal transduction pathway characterization in cell-based assays Structure-activity relationship (SAR) analysis of peptide modifications Receptor selectivity profiling and cross-reactivity studies In vitro metabolic signaling pathway investigation Peptide stability and proteolytic resistance research Storage & handling
Storage (Lyophilized): Store at -20°C in original sealed vial. Protect from light and moisture. Storage (Reconstituted): Store at 2-8°C for up to 14 days. For extended storage, prepare single-use aliquots and store at -20°C or -80°C. Avoid repeated freeze-thaw cycles. Reconstitution: Reconstitute with sterile water or sterile PBS using aseptic technique. Allow to dissolve completely without vigorous agitation. Stability: Lyophilized peptide stable for 24 months when stored at -20°C as directed. Handling: Wear appropriate personal protective equipment. Handle according to standard laboratory safety protocols for synthetic peptides. Research notes
Research Context: This compound serves as a reference material for investigating multi-agonist approaches in receptor pharmacology and comparative studies of incretin-based peptides. Reconstitution Guidelines: Typical working concentrations range from 0.1-10 μM depending on assay design and experimental objectives. Addition of 0.1% BSA may minimize peptide adsorption to laboratory plasticware. Structural Features: Engineered peptide sequence incorporating structural modifications to achieve balanced tri-agonist activity while maintaining proteolytic stability and receptor binding affinity. Mechanism: This synthetic peptide exhibits agonist activity at three distinct G protein-coupled receptors: glucagon-like peptide-1 receptor (GLP-1R), glucose-dependent insulinotropic polypeptide receptor (GIPR), and glucagon receptor (GCGR).

Been comparing vendors for Reta GLP-3 and NL has been the most consistent. Quality matches what they claim on the site, cake came apart easily with gentle swirling. Cold pack was still cold when...
