Biotin – Glucagon (1 – 29), bovine, human, porcine

TECHNICAL SPECIFICATIONS

1.MECHANISM OF ACTION

This conjugate functions identically to native glucagon by binding and activating the Glucagon Receptor (GCGR), a Class B G-protein coupled receptor primarily expressed in hepatocytes. Upon binding, the conjugate activates the Gs protein, stimulating adenylate cyclase and dramatically increasing intracellular cyclic AMP (cAMP) levels. This triggers protein kinase A (PKA) activation, leading to the phosphorylation of key enzymes that drive hepatic glycogenolysis and gluconeogenesis, resulting in elevated blood glucose. The covalently attached biotin moiety does not interfere with receptor binding or this signaling cascade. 

2.PRODUCT INDICATIONS

• Receptor Localization & Trafficking: Visualizing GCGR distribution and internalization in cells or tissues using streptavidin-conjugated fluorophores for microscopy (IHC, IF, live-cell imaging).

• Affinity Capture & Proteomics: Isolating glucagon-bound receptors or associated protein complexes from cell lysates using streptavidin-coated beads for mass spectrometry or Western blot analysis.

• Biosensor & Assay Development: Immobilizing the peptide on streptavidin-coated surfaces (SPR chips, ELISA plates, biosensors) for real-time binding kinetics studies, drug screening, or diagnostic assay development.

• In SituBinding Studies: Mapping active receptor sites in tissue sections (e.g., liver, pancreas) using biotin-streptavidin detection methods.

• Quantitative Receptor Analysis: Using the biotin tag for highly sensitive detection in quantitative flow cytometry or other analytical platforms to measure receptor expression levels.

• High-Throughput Screening (HTS): Serving as a tagged ligand in screening campaigns for GCGR agonists, antagonists, or allosteric modulators.

3.CLINICAL EFFICACY OF PRODUCT

• Research Utility: It is highly effective in the applications listed above, providing crucial mechanistic insights into glucagon receptor biology that cannot be obtained with the native peptide alone.

• Diagnostic Development: The biotin-streptavidin system is foundational to in vitrodiagnostics (IVD). This conjugate can be used to develop research-use-only (RUO) or prototype immunoassays for detecting glucagon receptors or autoantibodies in patient samples.

• Drug Discovery Support: Research using this tool aids in characterizing novel GCGR-targeting therapeutics (e.g., agonists for hypoglycemia, antagonists for diabetes/NASH) by enabling detailed studies of drug-receptor interactions.

• No Therapeutic Use: This conjugate is not administered to humans. Clinical efficacy data pertains to the glucagon/GCGR system itself, which is targeted by approved drugs like dasiglucagon (a stable glucagon analog for severe hypoglycemia) and investigational GCGR modulators.
