GLP-1 (7-36)-Lys(biotinyl) amide (human, bovine, guinea pig, mouse, rat)

GLP-1 (7-36)-Lys(biotinyl) amide is a universal biotinylated research reagent that includes the major active form of Glucagon-Like Peptide 1 (the 7-36 fragment) with a C-terminal lysine residue conjugated to biotin. This product is offered as a species-crossreactive conjugate, featuring sequences compatible with human, bovine, guinea pig, mouse, and rat GLP-1 receptors due to high sequence homology in this region.

1.MECHANISM OF ACTION

This biotinylated conjugate functions as a high-affinity, full agonist for the GLP-1 Receptor (GLP-1R) across multiple species. It binds specifically to the extracellular domain of GLP-1R, a Class B G-protein coupled receptor, and activates canonical downstream signaling. Receptor engagement stimulates Gs-protein coupling, activating adenylate cyclase and elevating intracellular cyclic AMP (cAMP). This triggers protein kinase A (PKA) and Epac2 pathways, leading to glucose-dependent insulin secretion in beta cells, suppression of glucagon release, slowed gastric emptying, and enhanced satiety signaling.

2.PRODUCT INDICATIONS

Multi-Species Receptor Studies: Ideal for comparative GLP-1R research across human, rodent (mouse, rat, guinea pig), and bovine models using a single, cross-reactive reagent.

Receptor Visualization & Trafficking: For immunohistochemistry (IHC), immunofluorescence (IF), and live-cell imaging of GLP-1R localization, expression, and internalization using streptavidin-fluorophore conjugates.

Affinity Purification & Proteomics: Isolating native GLP-1R complexes from tissue lysates or cell lines via streptavidin bead pull-down for mass spectrometry or Western blot analysis.

Biosensor & Binding Assay Development: Immobilizing the peptide on streptavidin-coated surfaces (SPR chips, ELISA plates, BLI sensors) for kinetic studies, ligand screening, and diagnostic assay development.

Flow Cytometry: Quantifying cell surface GLP-1R expression on live cells using streptavidin-conjugated fluorochromes.

High-Throughput Screening (HTS): Serving as a universal tagged ligand in screening campaigns for GLP-1R agonists, antagonists, or allosteric modulators across different species.

3.CLINICAL EFFICACY OF PRODUCT

Research & Diagnostic Tool Efficacy: Its efficacy is defined by its performance in the laboratory—specifically, its ability to bind GLP-1R with high affinity across species and enable sensitive detection, quantification, and isolation of the receptor in complex biological samples.

Enabling Translational Research: By facilitating detailed studies of GLP-1R biology in preclinical animal models (mouse, rat, guinea pig) and human systems, this tool contributes to the mechanistic understanding that underpins GLP-1-based therapies.

Supporting Drug Discovery: It is invaluable in characterizing lead compounds, performing receptor occupancy studies, and validating assay systems during the development of GLP-1R-targeting drugs like semaglutide, liraglutide, and tirzepatide.

Clinical Correlation: The GLP-1 pathway itself is the target of highly efficacious FDA-approved drugs for type 2 diabetes and obesity. This reagent helps bridge preclinical findings to human biology, but the conjugate itself is not a therapeutic.
